MATERIAL PROFILE / Individual substance
CAS: 61-82-5
Function: Individual chemical research reference
Compare this material →This material’s published information has not yet been verified by a human reviewer.
Human verification concerns the stated information and scope. It is separate from an EcoSafe score, certification or safety approval.Colorless to white, crystalline powder. [herbicide] [Note: Odorless when pure.] Source-checked chemical identity with NIOSH physical-property and occupational-hazard context. Supplier grade, manufacturing origin and EcoSafe assessment require separate review.
Chemistry: Amitrole
Listed supplier: Supplier not selected · substance baseline
Chemical identity only; purity, grade and supplier composition require separate documentation.
Identity snapshot: 2026-11-02 UTC.
CAS identity reference ↗13 of 16 defined fields have sourced information. This is data coverage, not a safety score, EcoSafe assessment or human-verification mark.
CAS cross-check: CAS 61-82-5 appears on the NIOSH card and in the returned PubChem CID’s synonyms. The CAS checksum and molecular-weight consistency were screened; variable-form and ambiguous matches were held out.
