Potassium Dichromate (CAS 7778-50-9) is a bright orange-red, water-soluble crystalline solid in the hexavalent chromium family that acts as a powerful oxidizing agent in acidic media, and it is used in chrome tanning, yellow chromate pigments, corrosion inhibitors for metal alloys, photographic sensitizers and laboratory oxidations.
Potassium Dichromate
Applications
Employed in chrome tanning for leather durability; in pigment production for yellow chromates; in corrosion inhibitors for metal alloys; in photographic sensitizers; and in laboratory oxidations for organic synthesis in chemical manufacturing.
Safety & Risks
Classified as carcinogenic (Category 1B) and mutagenic; causes respiratory sensitization and severe burns. Strict REACH regulations apply; equipped with exhaust ventilation, chemical suits, and chromium monitoring devices to limit occupational exposure below permissible limits.
Packaging
Contained in 25 kg UN-approved high-density polyethylene drums with hazard placards. Lock in segregated hazardous waste zones, away from reducing agents to avoid spontaneous combustion risks.
