Awaiting human verification

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.

Overview

Colorless to pale-yellow liquid with an aromatic, aniline-like odor. Source-checked chemical identity with NIOSH physical-property and occupational-hazard context. Supplier grade, manufacturing origin and EcoSafe assessment require separate review.

Chemistry: o-Toluidine

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 95-53-4 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.
