CAS number
The identifier used to confirm the chemical substance when names and abbreviations vary.
Reference layer for procurement teams
Check the term.
Then check the CAS.
A compact reference for buyers, formulators and logistics teams who need to confirm what a product identity or document actually means.
10 key terms
Less ambiguity before the first email.
TDS
Technical Data Sheet: controlled product specifications and physical properties for procurement and process review.
SDS
Safety Data Sheet: GHS-aligned hazard, handling, storage, transport and emergency information.
COA
Certificate of Analysis: test results for the actual batch being shipped.
Glycol ether
A solvent family based on glycol structures, commonly split into ethylene- and propylene-glycol series. End-capped diethers do not contain a free hydroxyl group.
Glycol ether ester
An ester derived from a glycol ether. Properties depend on the individual product; not every ester solvent is a glycol-ether ester.
Anthraquinone process
The industrial H₂O₂ process using a working carrier, main solvent and co-solvent in a hydrogenation–oxidation cycle.
Electronic grade
A purity and impurity-control level for electronics applications; the exact level is defined by the controlled TDS.
SEI film
Solid Electrolyte Interphase formed on a lithium-ion battery anode during initial cycling.
Dangerous goods
Transport classification that affects UN number, packaging, declarations, carrier acceptance and freight surcharges.
