D-Galactosamine hydrochloride, min. 98 %, for biochemistry, 1 g, glass

D-Galactosamine hydrochloride is a biochemical-grade amino sugar derivative supplied at a minimum purity of 98 % for biochemistry applications. It carries the empirical formula C₆H₁₄ClNO₅, CAS number 1772-03-8 and EG number 217-198-1, with a molar mass of 215,64 g/mol and a density of 0,35 g/cm³. Researchers employ D-galactosamine hydrochloride in cell-culture models, liver-related biochemical assays and the preparation of modified oligosaccharides or glycoconjugates. The defined minimum assay supports reproducible experimental design where amino sugar hydrochloride salts are required as substrates, inhibitors or reference compounds., with a net weight of approximately 0,011 kg, provides a convenient amount for method set-up and multiple small-scale incubations without unnecessary surplus. As a classic building block in carbohydrate chemistry and glycobiology, this hydrochloride salt integrates into standard laboratory protocols alongside related hexosamines and nucleotide-sugar precursors. Its biochemistry designation underscores suitability for life-science workflows that prioritise consistent quality and clear analytical identity.
