Chromium(III) Sulfate CAS 10101-53-8

FAQ - Technical & Supply Chain

• Q:

  Is Chromium(III) Sulfate CAS 10101-53-8 the same product as Basic Chromium Sulfate?

  A: No. CAS 10101-53-8 identifies chromium(III) sulfate, also called chromic sulfate, Cr2(SO4)3. It should not be confused with chromium(VI) chromates or dichromates, and a basic chromium sulfate tanning grade must be confirmed as a separately specified material rather than assumed from the CAS alone.
• Q:

  What is Chromium(III) Sulfate used for?

  A: It is a trivalent chromium sulfate used as a chromium(III) source in industrial and inorganic processes. This page does not establish a Basic Chromium Sulfate tanning grade or a leather-tanning application, so the intended process should be confirmed against the current product-specific specification.
• Q:

  Which form and specifications should be agreed for Chromium(III) Sulfate?

  A: Confirm whether the offer is anhydrous solid, hydrated material or a stated aqueous solution, then agree Cr(III) content and reporting basis, sulfate, water or specific gravity, insoluble matter, chloride, iron, other metals and the Cr(VI) limit with the test methods.
• Q:

  Why is the Cr(VI) limit important for Chromium(III) Sulfate?

  A: Chromium(III) sulfate is a trivalent chromium salt, but the Cr(VI) limit should still be controlled and confirmed for regulatory and safety purposes. Use the current product-specific specification and local regulatory requirements to assess handling, storage, waste management and any workplace exposure controls.
• Q:

  What should be confirmed before ordering Chromium(III) Sulfate?

  A: Confirm the exact chromium material, form or solution concentration, packaging and destination requirements. Request the current product-specific specification, and review handling, storage and local regulatory suitability before quotation and delivery.
