Grade: br

Content: ≥ 98.0% (GC)

Water dissolution test: qualified

Specific rotation: +95.5 ~ +98.0 º (c=10, H2O)

PH：5.5～8.0

Oxalic acid test: qualified

Physicochemical properties: white or slightly yellow crystalline particles or powder, odorless, slightly salty, easily soluble in water (about 7ml water can dissolve 1g). The dry state is stable in the air. When it is in aqueous solution, it is easy to deteriorate in the presence of air, trace metals, heat and light. Melting point: 154-164 ℃

Purpose: biochemical research. Cosmetics antioxidant. It can consume oxygen in cosmetics, reduce high valence metal ions, transfer the oxidation-reduction potential to the reduction range, and reduce the production of adverse oxidation products. It can also be used as anti-corrosion color aid
