Sanshool identity Establish which molecular structure the registry entry and each candidate sample denote.
Molecular boundary
Resolve connectivity and the geometric identity represented by the alpha designation.
Structure assignment
A name match is insufficient unless the associated structure specifies the hydroxylated substituent and relevant double-bond geometry.
- What complete stereochemistry-explicit structure defines hydroxy-alpha-sanshool in this model? definition
- Which structural differences separate it from hydroxy-beta-sanshool and alpha-sanshool? boundary
Identity evidence
Connect external identifiers and sample measurements to the same molecular entity.
Reference and sample match
Identifiers, reference standards and analytical assignments must agree at the isomer level.
- Which CAS, PubChem and EC records have been checked against the explicit structure rather than the substance name alone? provenance
- What chromatographic and spectroscopic evidence distinguishes this sample from co-occurring sanshool isomers? measurement
Sample composition Represent how much hydroxy-alpha-sanshool is present and what accompanies it.
Target content
Quantify hydroxy-alpha-sanshool independently of total alkylamide content.
Assay basis
Purity requires a stated measurement basis and sufficient selectivity for the target isomer.

- Does the method resolve hydroxy-alpha-sanshool from other components sufficiently to calculate target-specific concentration? measurement
Origin and accompanying material
Track source-dependent constituents relevant to interpreting the isolated sample.
Matrix and impurities
Botanical or synthetic origin informs which accompanying materials need investigation, without redefining molecular identity.
- Was the sample isolated from an identified botanical source or produced synthetically, and which lot records support that origin? provenance
- Which other sanshools, residual solvents or unidentified components are present at levels relevant to the intended use? measurement
Physical state and integrity Assess the usable condition of neat material and preparations over time.
Phase and dissolution
Record observed phase, thermal behaviour and dissolution under explicit conditions.
Available dissolved compound
Physical-property values and preparation concentrations require conditions and direct evidence applicable to hydroxy-alpha-sanshool.
- What measured phase and thermal-transition data exist, and do heating observations indicate a transition or decomposition? measurement
- At the intended solvent composition and temperature, how much hydroxy-alpha-sanshool remains dissolved? measurement
Storage-dependent change
Determine whether handling changes target content or isomer distribution.
Integrity and retest
Storage decisions should follow measured changes; susceptibility to particular degradation pathways remains a research question until demonstrated.
- How do light, oxygen, temperature and storage duration affect target recovery and the resolved isomer profile? measurement
- Which measured acceptance limits require retesting, replacing or rejecting a stored preparation? action
Sensory and neuronal activity Link hydroxy-alpha-sanshool exposure to experimentally supported sensory and cellular responses.
Sensory response
Represent tingling-related effects with exposure conditions and endpoint definitions.
Exposure-response link
Research connects hydroxy-alpha-sanshool with sensory-neuron activity relevant to tingling, but individual experiments do not establish universal human thresholds. [Primary study](https://pubmed.ncbi.nlm.nih.gov/20335471/)
- Which species, tissue, exposure route, concentration and response endpoint support the reported sensory effect? provenance
- How were responses attributable to purified hydroxy-alpha-sanshool separated from solvent and other pepper constituents? measurement
Channel mechanisms
Keep molecular target evidence specific to the experimental system.
Potassium-channel evidence
Primary research reports inhibition of KCNK3, KCNK9 and KCNK18; this supports a mechanism to evaluate rather than a complete explanation of every sensory response. [Primary channel study](https://pmc.ncbi.nlm.nih.gov/articles/PMC3072296/)
- Which channel subtype, expression system and concentration-response measurements support each inhibition claim? measurement
- What evidence connects those channel effects to the observed sensory response, and which competing mechanisms remain unresolved? boundary
Handling and use eligibility Determine what the evidence permits an agent to conclude about handling and intended application.
Exposure and hazard
Resolve hazards for the actual concentration, physical form and exposure route.
Substance-specific hazard record
Hazard classifications and exposure limits must be verified for this substance or explicitly identified as unavailable.
- Which current safety data and primary toxicological evidence apply to the verified hydroxy-alpha-sanshool identity and sample form? provenance
- What handling controls follow from documented hazards, concentration and route of exposure? action
Application boundaries
Separate evidence for analytical, research and food-related uses.
Use-specific release
Suitability is an evidence-backed decision for a particular application and jurisdiction, rather than an intrinsic consequence of botanical origin.
- What dated regulatory evidence addresses isolated hydroxy-alpha-sanshool for the proposed use and jurisdiction? provenance
- Which identity, purity, stability and documentation requirements must this lot meet for that application? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

What it is Filled
Hydroxy-alpha-sanshool is a naturally occurring unsaturated fatty acid amide found in Zanthoxylum peppers that contributes to their characteristic tingling and numbing oral sensations.
In scope
- Molecular identity and differentiation from other sanshools
- Sample purity, isomer distribution and concentration
- Physical properties, dissolution and storage-dependent condition
- Evidence connecting measured exposure to sensory or neuronal responses
- Substance-specific handling and jurisdiction-dependent use constraints
Out of scope
- Zanthoxylum species, cultivation and whole-pepper composition
- Complete pepper extracts, seasonings and finished food formulations
- Extraction and synthesis processes as production systems
- General models of sensory neurons and ion channels
- Clinical treatment protocols and therapeutic efficacy claims
Why it exists Filled
Enable an agent to identify hydroxy-alpha-sanshool, assess the composition and condition of a sample, and determine whether evidence supports its intended analytical, sensory or experimental use.
Distinguishing features Filled
- Require a structure-resolved identity for hydroxy-alpha-sanshool; the label 'sanshool' alone does not distinguish the hydroxylated alpha compound from related substances.
- Check molecular formula C16H25NO2 against the assigned identity, while recognising that formula alone cannot distinguish geometric isomers. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/Hydroxy-Alpha-Sanshool)
- Distinguish hydroxy-alpha-sanshool from hydroxy-beta-sanshool using evidence resolving double-bond geometry, rather than nominal molecular mass alone.
- Distinguish isolated hydroxy-alpha-sanshool from pepper extracts by quantified target content and a resolved profile of accompanying alkylamides.
- Treat tingling or neuronal excitation as supporting activity evidence rather than a chemical identity test; published experiments examine responses under specific exposure conditions. [Primary sensory study](https://pubmed.ncbi.nlm.nih.gov/20335471/)
What robots and AI may and may not do Filled
Must not
- Recommend concentrated extracts for medical use without evidence and a clinician's decision.

Only with a human decision
- Adding concentrated extracts to food or cosmetic products.
- Testing it on people in sensory studies.
May
- Identify hydroxy-alpha-sanshool as the tingling compound of certain peppers, citing sources.
- Report the source, purity and storage of an extract or reference sample.
Moral aspects Filled
