Dothiepin identity Establish which chemical entity a dothiepin reference or sample represents.
Names and identifiers
Reconcile registry identity with external chemical records.
Dosulepin name resolution
Record evidence linking dothiepin and dosulepin while preserving the exact chemical scope of each external identifier.
- Which authoritative record establishes that the encountered dothiepin or dosulepin name denotes this registered substance? definition
- Do the proposed CAS number, PubChem CID and EC number identify the same structure, configuration and salt status? provenance
Structure and form boundaries

What it is Filled
Dothiepin, in this sense, denotes the pair of cis-trans geometric isomers of a sulfur-containing tricyclic compound with a dimethylaminopropylidene side chain, rather than a particular medicinal substance or formulation.
In scope
- Name reconciliation and structure-specific identifiers distinguish the isomer pair from individual isomers and medicinal dosulepin records.
- Free-base identity and geometric configuration distinguish the two isomers and their relationships to salt forms.
- Batch composition, assay, impurities and material grade include evidence of isomer composition.
- Physical properties and stability are attributed to the identified isomer or documented mixture under recorded conditions.
- Substance hazards and jurisdiction-specific restrictions are attributed to the relevant isomer, mixture or salt using dated evidence.
Out of scope
- Finished tablets, capsules, brands and their excipient compositions
- Patient-specific diagnosis, prescribing, dosing and treatment monitoring
- Manufacturing plant design and synthesis process execution
- Independent models of metabolites, degradation products or related antidepressants
- Commercial suppliers and distribution organisations
Why it exists Filled
Enable an agent to recognise dothiepin, assess the identity and condition of a material containing it, and determine evidence-supported handling or use constraints.
Distinguishing features Filled
- The given sense denotes both cis-trans isomers rather than selecting a single configuration or assuming a mixture of fixed composition.
- The shared sulfur-containing dibenzothiepin structure and dimethylaminopropylidene side chain distinguish the pair from other tricyclic compounds.
- The free-base formula C19H21NS differs from the hydrochloride formula C19H22ClNS, so salt identity must be explicit when comparing properties.
- Molecular formula alone cannot distinguish the geometric isomers, and an individual Z-dothiepin record does not represent the whole pair.
- A dosulepin medicine record describes its declared ingredient and formulation rather than establishing the identity or properties of both isomers.
What robots and AI may and may not do Filled
Must not
- Prescribe, start, stop or change doses of dosulepin for a person.
- Provide any information that helps a person use it to harm themselves or others.
- Recommend combining it with other substances.
- Ignore signs that a person may be at risk of suicide.
Only with a human decision
- Any treatment decision, made by the prescriber.
- Responding to a person in crisis, which needs urgent human and emergency support.
May
- Explain what dosulepin is and its approved uses, citing official product information.
- Report documented safety warnings, including the risk in overdose.
Moral aspects Filled
- Antidepressants help many people, yet this one is dangerous in overdose, so care is essential.
- People with depression deserve treatment without stigma.
Who is affected
- People with depression
- Families
- Prescribers
Owners Filled
Steward
Chemical data curators maintain records of the isomer pair, while material custodians are responsible for records of particular samples.
Master systems
- Chemical identity registries distinguish the isomer pair from individual isomers and salt forms.
- Material composition records document the isomer composition of particular samples.
- Medicines regulator product registers provide related medicinal context rather than defining the isomer pair.

- Material form: Free base; hydrochloride; other evidenced salt; mixture; unresolved
- Geometric configuration: E; Z; measured mixture; unspecified

- Related-substance profile: Individual and total impurities in % or mg/kg, with method and quantification limits
- Physical condition: Observed phase, appearance and solid-form assignment at recorded temperature and pressure
- Thermal behaviour: Melting, transition or decomposition temperature in °C; boiling temperature only with pressure and evidence

- Grade and disposition: Documented grade and intended use; pending assessment; released; quarantined; rejected
- Applicable hazard and regulatory evidence: Dated SDS, classification, exposure-limit source and jurisdiction-specific authority record
Recognition required Filled
- Appearance alone cannot distinguish the cis-trans isomers or establish their proportions in a material.
- Medicine packaging and imprints identify a labelled product but do not establish the chemical identity or composition of the isomer pair.
Capabilities and actions required Filled
- Resolve dothiepin and dosulepin references to the registered substance while flagging ambiguous salt or configuration assignments.
- Compare a batch with an evidenced specification and identify missing tests before release.
- Calculate free-base-equivalent content when salt stoichiometry, water content and assay basis are established.
- Select analytical and storage conditions supported for the identified material form.
- Flag degradation, impurity or identity discrepancies for quarantine and investigation.
- Route medicinal-use questions to a linked product or clinical model with the relevant substance constraints.
Hazards and failure modes required Filled
- Attributing medicinal dosulepin properties to both isomers without supporting evidence can misrepresent their hazards.
- Medicinal dosulepin overdose can cause life-threatening heart rhythm problems and seizures.
- Medicinal dosulepin side effects include drowsiness that can impair driving.
Standards and interfaces required Filled
- The Anatomical Therapeutic Chemical classification maintained by the WHO Collaborating Centre for Drug Statistics Methodology lists dosulepin under code N06AA16.
Context of use required Filled
- This substance is encountered in pharmaceutical reference materials, analytical laboratories and medicinal products containing its hydrochloride salt.
- Material identification distinguishes the stated isomer composition and salt form because a substance name alone does not establish the composition of a sample.

- Wikipedia: Dosulepin - general description of the item
Open questions
- Does the authoritative registry intend vr.tr.dothiepin to specify a particular geometric configuration or a broader parent-substance identity, and is there an existing world model to reuse?
- Which CAS and EC identifiers are verified for the intended configuration and free-base or hydrochloride form, and which identifiers are ambiguous?
- Which current compendial or otherwise qualified specifications establish assay methods, related-substance panels, isomer limits and grade requirements?
- What measured phase, melting or decomposition, solubility and storage-stability data are available for each relevant form, and is any boiling-point value experimentally meaningful?
- Which current jurisdiction-specific hazard classifications, occupational exposure limits and use restrictions apply to the actual material and proposed activity?
