Chromic Anhydride, identifiable by CAS 1333-82-0, functions as the anhydrous precursor to chromic acid used primarily as the principal electrolyte in chromium electroplating and metal finishing processes. Chemically defined as Chromium(VI) Oxide, these dark red, deliquescent flakes or crystals serve as a powerful oxidizing agent in organic synthesis and a corrosion inhibitor in industrial water treatment. The substance, often referred to as Chromium Trioxide or Chromic Acid Flakes in plating protocols, acts as the source of hexavalent chromium for hard chrome coatings and aluminum anodizing baths. We facilitate bulk supply of this strong oxidizer with competitive factory pricing, capable of meeting customized specifications for sulfate content, backed by comprehensive MSDS, TDS, COA documentation.
