Core data coverage: 81.3%

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 7719-12-2 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.
