Sourcing Potassium Dichromate? ChemicalDekho connects you with primary manufacturers like Vishnu Chemicals and major industrial distributors. Access high-purity orange crystals for specialized industrial synthesis.
Potassium Dichromate (CAS 7778-50-9) is a potent oxidizer essential for the metal finishing industry, where it is used for chromate conversion coatings and brass cleaning. In the textile and leather sectors, it serves as a mordant and tanning agent. It is also a fundamental reagent in analytical chemistry for COD testing and titrations.
**SAFETY NOTE:** This chemical is a strong oxidizer and is classified as carcinogenic and mutagenic. Supply is restricted to industrial users with proper handling protocols.

May intensify fire; oxidizer. Fatal if inhaled. Toxic if swallowed. Causes severe skin burns and eye damage. May cause genetic defects and cancer. May damage fertility.
The intense orange color is due to the presence of the dichromate ion [Cr2O7]2-, where Chromium is in its +6 oxidation state.
No. Chromic Acid (CrO3) is much more acidic and dangerous. Potassium Dichromate is a salt of chromic acid and is generally used in different industrial processes.
It is extremely toxic and carcinogenic. We strongly discourage home use; it is strictly an industrial chemical.
In wastewater testing, it acts as the primary oxidant to break down organic matter so that the 'Chemical Oxygen Demand' (COD) can be measured.
