Definitions written for AI citation and developer onboarding. Each term links to ChemCloud MCP Tools where applicable.
A unique numeric ID from Chemical Abstracts Service for a chemical substance (e.g. 50-00-0). Trade, regulatory, and R&D workflows use CAS to avoid ambiguous trade names.
On ChemCloud: search_compound, get_compound_by_cas. See also the Chinese chem-data API / CAS notes.
UN-backed system for harmonized hazard classification and labelling, used in cross-border trade and compliance communication.
On ChemCloud: hazard / compliance Skills and compound Tools can support Q&A; treat outputs as data assistance, not legal advice.
SDS is the current term; MSDS is a common legacy name. Sheets cover hazard identification, first aid, fire-fighting, spill response, exposure controls, and more.
On ChemCloud: get_compound_msds; MSDS-oriented Skills on the Skill plaza.
Simplified Molecular Input Line Entry System — a one-line ASCII encoding of molecular structure, useful for cheminformatics and database search.
EU Classification, Labelling and Packaging regulation, aligned with GHS principles for the EU market. Platform data is read-only and is not legal counsel.
A unique Chemical Abstracts Service identifier for a substance. Use ChemCloud Tools such as search_compound and get_compound_by_cas.
Globally Harmonized System for classifying and labelling chemical hazards.
Same document family; SDS is modern naming, MSDS is legacy. ChemCloud exposes get_compound_msds.
