One identifier that cannot be misread.
Chemical names vary between suppliers and between countries. The CAS Registry Number does not, which is why purchasing specifications are written against it.

Formulated blends
A mixture does not have a single CAS number. The safety data sheet for each product lists the registry numbers of its hazardous components in Section 3.

A CAS Registry Number identifies a single substance. "Caustic soda", "lye", "sodium hydrate", and "sodium hydroxide" are the same thing — 1310-73-2 — and a purchasing specification written against the number cannot be misread the way a name can.
That matters most at two moments: when you are cross-referencing a competitor quote against ours, and when a regulator or an auditor asks what exactly is on site. Both go faster with a number.
What the number does not tell you
CAS identifies the substance, not the grade, the concentration, or the specification. Technical grade and USP grade sulfuric acid share a registry number and are not interchangeable — the difference sits in trace impurities the number says nothing about.
So use the CAS to confirm you are comparing the same substance, then compare grade, assay, and Certificate of Analysis to confirm you are comparing the same product.
If your approval process needs something that is not here, one email gets it.
Certificates, insurance, registrations, safety data sheets, and completed supplier questionnaires. Standard documents go out the same business day.
