chlorosarin
Enable an AI agent to recognize chlorosarin, evaluate evidence about its material state, and identify the specialist review required for decisions involving it.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Chlorosarin identity Establish what chemical the registry name denotes and how related names differ.
Names and identifiers
Reconcile common names, chemical names, and external records.
Canonical identity match
Require agreement between chlorosarin's chemical name, CAS identifier, and referenced identity record.
- Which authoritative record establishes that this name denotes O-isopropyl methylphosphonochloridate? definition
- Do the supplied identifiers resolve to the same structure, and which records were checked? provenance
Related substance boundaries
Keep nearby chemical identities distinct without rebuilding their models.
Sarin and chlorosoman distinction
Use the defining substituent differences to test identity rather than relying on name resemblance.
- Does the referenced structure support chlorosarin rather than sarin or chlorosoman? boundary
- Does the source specify stereochemistry, leave it unspecified, or describe a mixture? definition
Chlorosarin in material Separate the substance identity from claims about particular samples.
Sample identity evidence
Evaluate existing reports supporting chlorosarin's presence.
Reported versus confirmed presence
Record whether the name comes from a label, historical attribution, or specialist confirmation.
- What evidence supports chlorosarin's presence in this particular sample? provenance
- Does the report distinguish chlorosarin from related substances and state its identification limitations? measurement
Composition and purity
Represent chlorosarin content and other constituents without conflating concentration and purity.
Composition basis
Tie each content claim to its sample, reporting basis, uncertainty, and date.

- Which accompanying constituents are identified, and how much composition remains unresolved? measurement
Physical state and change Represent conditional observations and uncertainty about changes in chlorosarin-containing material.
Conditional properties
Bind physical descriptions and constants to their evidential and measurement conditions.
Chlorosarin-specific property support

- Are temperature, pressure, units, uncertainty, and sample composition recorded where relevant? measurement
Sample change evidence
Track evidence that a material's composition or identity attribution has changed.
Current identity validity
Avoid treating an earlier chlorosarin identification as a permanent description of all sample contents.

Direct and analogue evidence
Identify the actual substance and evidence type behind a hazard claim.
Hazard attribution
Keep chlorosarin-specific observations separate from predictions and sarin-based references.

Associate chlorosarin material claims with accountable sample and custody records.
Traceable material attribution
Ensure that identification, composition, and regulatory assertions concern the same material.

Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
Chlorosarin is O-isopropyl methylphosphonochloridate, an organophosphorus compound structurally related to sarin by having chlorine in place of its phosphorus-bound fluorine.
In scope
- Chemical identity and reconciliation of names and identifiers
- Distinction from sarin, chlorosoman, and mixtures containing chlorosarin
- Sample composition, purity, phase, and characterization uncertainty
- Chlorosarin-specific hazard evidence and unresolved classifications
- Chemical Weapons Convention identity and links to applicable oversight
Out of scope
- Synthesis, purification, or conversion procedures
- Weapon formulation, dissemination, or performance
- Operational storage, transport, and disposal procedures
- Clinical diagnosis and treatment of exposed people
- Facility licensing and institutional compliance workflows
- Independent models of sarin, chlorosoman, and transformation products
Why it exists Filled
Enable an AI agent to recognize chlorosarin, evaluate evidence about its material state, and identify the specialist review required for decisions involving it.
Distinguishing features Filled
- Match chlorosarin to O-isopropyl methylphosphonochloridate and CAS 1445-76-7; a similar common name alone is insufficient. [OPCW Schedule 1](https://www.opcw.org/chemical-weapons-convention/annexes/annex-chemicals/schedule-1)
- Distinguish it from sarin by chlorine rather than fluorine bonded to phosphorus. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/102124)
- Distinguish it from chlorosoman by the O-isopropyl group rather than the O-pinacolyl group. [OPCW Schedule 1](https://www.opcw.org/chemical-weapons-convention/annexes/annex-chemicals/schedule-1)
- Reconcile molecular formula C4H10ClO2P and PubChem CID 102124 with the named structure; formula alone does not establish identity. [PubChem](https://pubchem.ncbi.nlm.nih.gov/compound/102124)
- Distinguish the molecular substance from a sample that merely contains it; reported detection does not establish sample purity.
What robots and AI may and may not do Derived, awaiting review
Must not
- The Chemical Weapons Convention, adopted by the Conference on Disarmament and administered by the Organisation for the Prohibition of Chemical Weapons, covers chlorosarin under Schedule 2.
- Visual appearance cannot reliably distinguish chlorosarin from similar chemicals, so identification requires specialist analytical evidence.
Only with a human decision
- Clinical diagnosis and treatment of exposed people
- Contact with moisture can produce corrosive decomposition products that threaten people and equipment.
May
- Reconcile a chlorosarin name or identifier against authoritative chemical records
- Compare a reported identity with sarin and chlorosoman to flag misidentification
- Attach existing specialist characterization reports to a particular sample
- Separate verified chlorosarin measurements from estimates and analogue-derived claims
- Flag unresolved identity, hazard, or authorization evidence for qualified review
- Link a sample record to its custody, incident, and regulatory records
