Potassium bromate

Potassium bromate (CAS 7758-01-2, EC 231-829-8, E924) is an inorganic bromate salt supplied as a white crystalline powder. It is registered under the E-number E924 and is also referenced as potassium trioxobromate or bromicacid potassium salt in technical documentation.

In flour treatment, potassium bromate acts as an oxidising agent that strengthens gluten networks by forming disulfide bonds between protein chains, improving dough elasticity and oven rise. In water treatment, it functions as a disinfection byproduct control reference standard and as an antimicrobial oxidiser in specific process water applications.

Potassium bromate is available in technical and food-grade forms, with the E924 designation applicable within permitted regulatory frameworks. It falls under REACH registration requirements and is classified under HS code 28299000. Buyers should confirm current approval status in their target market, as permitted uses vary by jurisdiction across the EU and globally.
