Is Anhydrous Chromium(III) Chloride interchangeable with Chromium(III) Chloride Hexahydrate?

No. Anhydrous chromium(III) chloride, CAS 10025-73-7, and chromium(III) chloride hexahydrate have different water content, formula mass and handling behavior. A hydrate should not be accepted as an anhydrous replacement without recalculating the chromium or chloride basis and approving the specification.

Which specifications matter for Anhydrous Chromium(III) Chloride?

Agree CrCl₃ assay, moisture, insoluble matter, iron, other metals, particle form and the test methods. Confirm a moisture-protective package and storage conditions because hydration changes the delivered composition. The COA should identify anhydrous basis, batch date and the analytical method used.

Anhydrous Chromium(III) Chloride CAS 10025-73-7

Anhydrous Chromium(III) Chloride, CAS 10025-73-7, is also known as chromium trichloride or chromic chloride. It requires grade selection by anhydrous identity, hydration state, assay basis, water and insoluble-matter limits, particle form, dry packaging and intended process for selected chromium chemistry, catalyst and industrial process uses. Request current TDS, COA, SDS and packaging information.

Product Description

Product name: Anhydrous Chromium(III) Chloride

Appearance: violet to purple crystalline solid; confirm physical form on the offered specification

Water behavior: the anhydrous material is moisture-sensitive; confirm hydration state, handling and dissolution requirements

Chemical formula: CrCl₃

Molar mass: 158.36 g/mol

CAS Number: 10025-73-7

Anhydrous Chromium(III) Chloride, CAS 10025-73-7, is CrCl₃. It is not chromium(III) chloride hexahydrate, CAS 10060-12-5.

Identity boundary: specify anhydrous material in the RFQ; hydrated chromium(III) chlorides require a separate CAS and specification.

Physical form: anhydrous chromium(III) chloride is violet to purple; green hydrated-looking material must not be used to represent CAS 10025-73-7.

Applications: selected chromium chemistry, catalyst systems and industrial processes; confirm anhydrous identity, particle form and process-specific impurity limits.

Confirm on the offered specification and lot COA: anhydrous identity, hydration state, assay basis, water and insoluble-matter limits, particle form, dry packaging and intended process.

Procurement checks:

Confirm on the offered specification and lot COA: assay basis, water and insoluble-matter limits.

Packaging: confirm dry, moisture-excluding packaging and handling for the required quantity and destination.

Documents: request the current specification, TDS, lot COA and SDS; no fixed assay, package or origin is established on this page.
