Product Introduction

1,3-Dihydroxyacetone (DHA) is a naturally occurring tri-carbon ketose with molecular formula (mathbf{C_3H_6O_3}) and molecular weight of 90.07 g/mol.Manufactured in strict accordance with in-house enterprise standards, our product is white to off-white crystalline powder. Its assay is ≥98.0% with actual tested purity at 99.2%, moisture ≤0.4% (actual: 0.20%), and residue on ignition ≤0.4% (actual: 0.04%). Contents of heavy metals, iron, arsenic and other impurities are controlled within specified limits. The chemical property remains stable under proper storage, yet moisture-proof and light-shielded storage is required.

Product Advantages
