Chemical identity and isomers Recognise chlorfenvinphos while preserving distinctions between its substance record and individual geometric isomers.
Structure and identifiers
Connect the registry entry to independently verifiable chemical records.
Identifier scope
Record each identifier with its represented structure and stereochemical specificity; do not accept name similarity as identity evidence.
- Which structure and stereochemical scope does each CAS, PubChem and EC record represent? definition
- Which authoritative record supports each mapping to vr.tr.chlorfenvinphos? provenance
Geometric isomer composition
Represent E and Z explicitly within the registered thing.
Isomer assignment
Preserve original isomer terminology and require evidence before translating historical cis/trans or alpha/beta labels into E/Z assignments.
- Does the material contain E, Z or a measured mixture, and how were those assignments established? measurement
- Can the source's historical isomer labels be mapped unambiguously to E/Z structures? boundary
Technical material and quality Describe the actual chlorfenvinphos material rather than an idealised pure substance.
Assay and grade
Separate total active content, isomer proportions and non-active constituents.
Lot composition
Technical-material purity is source-dependent: historical ATSDR and FAO descriptions report different compositions. Treat these as examples rather than acceptance limits. [ATSDR chemical information](https://www.ncbi.nlm.nih.gov/books/NBK594527/) [FAO identity](https://www.fao.org/4/w5897e/w5897e0w.htm)
- What are the lot's total E-plus-Z assay, individual isomer fractions and reporting basis? measurement
- Which certificate, sampling procedure and specification support the assigned grade? provenance
Impurities and deterioration
Track departures from the material's initial specification.
Quality change
Record impurities, water content and transformation products separately from chlorfenvinphos; assess changes against the intended use.
- Which measured impurities or transformation products explain any loss of active content? measurement
- What evidence requires retesting, quarantine or rejection of this lot? action
Physical state and storage stability Tie chlorfenvinphos properties and stability to the material and conditions tested.
Conditional physical properties
Record comparable measurements with their experimental context.
Property applicability
Retain purity, isomer composition and pressure with thermal data; distinguish measured solubility from qualitative descriptions such as insoluble.
- Which phase, density, solubility and vapour-pressure measurements apply to this material and temperature? measurement
- Does a reported boiling value describe atmospheric boiling, reduced-pressure boiling or decomposition? boundary
Storage and compatibility
Connect exposure history and contact materials to stability decisions.
Container and condition suitability
Hydrolysis requires attention to aqueous conditions and alkalinity; the safety card also reports attack on several metals and decomposition on heating. [ATSDR chemical information](https://www.ncbi.nlm.nih.gov/books/NBK594527/) [ICSC 1305](https://chemicalsafety.ilo.org/dyn/icsc/showcard.display?p_card_id=1305&p_lang=en)

- Which current GHS classifications apply to the substance in the relevant jurisdiction? definition
Exposure assessment
Evaluate the actual handling scenario and applicable benchmarks.

- Which sourced exposure limits, averaging periods and control requirements apply? action
Environmental fate and residue evidence Connect chlorfenvinphos transformation and partitioning to defensible residue results.
Environmental transformation
Preserve matrix and experimental conditions for fate evidence.
Conditional persistence
FAO reports hydrolysis results separately by isomer and pH; a single universal persistence value would discard relevant conditions. [FAO physicochemical information](https://www.fao.org/4/w5897e/w5897e0w.htm)
- What hydrolysis, photolysis or biodegradation measurements apply to the relevant matrix and conditions? measurement
- Which transformation products and aquatic-effect endpoints require separate linked records? boundary
Residue identification and quantification
Establish what an analytical result actually measures.
Analytical result scope
Require matrix validation, analyte definition and reference-standard traceability before treating a reported residue as confirmed chlorfenvinphos.
- Does the method resolve E and Z, report their sum or include other compounds in a defined residue total? definition
- What recovery, detection limit, quantification limit and uncertainty support the result in this matrix? measurement
Legal status and material disposition Determine which activities are supported by current, applicable legal and operational evidence.
Jurisdictional authorisation
Attach scope and effective dates to permissions and restrictions.
Activity-specific status
Distinguish active-substance status from individual product approval and from research, import, possession or disposal permissions.
- Which official decision governs the proposed chlorfenvinphos activity, jurisdiction and date? provenance

What it is Filled
Chlorfenvinphos is a synthetic organophosphate insecticide and acaricide whose toxic action results from inhibition of acetylcholinesterase.
In scope
- Chemical identity and identifier mappings for chlorfenvinphos and its E/Z forms
- Lot-specific active-substance content, isomer proportions, impurities and degradation
- Physical properties tied to composition, temperature, pressure and measurement method
- Cholinesterase inhibition, exposure pathways and environmental hazards
- Analytical confirmation and interpretation of chlorfenvinphos residues
- Substance-level storage, transport, disposal and regulatory constraints
Out of scope
- Commercial pesticide formulations, including their solvents, co-actives and product registrations
- Manufacturing routes and process operating instructions
- Pest-control application schedules and efficacy programmes
- Clinical diagnosis and treatment of organophosphate poisoning
- Environmental sites and their complete contamination histories
Why it exists Filled
Enable an AI agent to recognise chlorfenvinphos, assess the identity and condition of a particular material, and determine which handling, analytical or regulatory decisions have sufficient evidence.
Distinguishing features Filled
- Confirm the 2-chloro-1-(2,4-dichlorophenyl)vinyl diethyl phosphate structure and formula C12H14Cl3O4P; a similar pesticide name is insufficient. [FAO identity](https://www.fao.org/4/w5897e/w5897e0w.htm)
- Distinguish the E/Z substance identity, CAS 470-90-6, from Z-isomer CAS 18708-87-7 and E-isomer CAS 18708-86-6. [FAO identity](https://www.fao.org/4/w5897e/w5897e0w.htm)
- Check the phosphate structure rather than inferring identity from organophosphate activity; cholinesterase inhibition alone cannot distinguish chlorfenvinphos from other inhibitors.
- Require measured active content and isomer composition to distinguish technical chlorfenvinphos from a formulated pesticide or an individual-isomer reference standard.
