CAS 96-26-4 — 1,3-Dihydroxyacetone

1,3-Dihydroxyacetone (DHA) is a naturally occurring carbohydrate and the primary active ingredient in self-tanning products, where it reacts with skin amino acids to produce a sunless tan. It is also used in cosmetics, pharmaceuticals, and as a reagent in biochemical research. This white crystalline solid has a CAS number of 96-26-4, a molecular formula of C3H6O3, and a molecular weight of 90.1 g/mol. It is stable at ambient storage conditions but requires careful handling, as indicated by its warning signal word for potential skin or eye irritation. Molekula supplies 1,3-Dihydroxyacetone from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
