CATO supplies (2R,3R,4S,5R,6R)-2-azido-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol 35899-89-9 beta-D-Galactopyranosyl azide (CAS 35899-89-9), a certified reference material (molecular formula C6H11N3O5, MW 205.17 g/mol) for analytical method development and quality control.
(2R,3R,4S,5R,6R)-2-azido-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol 35899-89-9 beta-D-Galactopyranosyl azide (C6H11N3O5) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
