CATO supplies 33639-78-0 Benzyl 2-acetamido-3,4-di-O-acetyl-2-deoxy-6-O-(2,3,4-tri-O-benzyl-6-deoxy-alpha-L-galactopyranosyl)-alpha-D-glucopyranoside DTXSID90747098 (CAS 33639-78-0), a certified reference material (molecular formula C46H53NO12, MW 811.91 g/mol) for analytical method development and quality control.
The molecular framework of 33639-78-0 Benzyl 2-acetamido-3,4-di-O-acetyl-2-deoxy-6-O-(2,3,4-tri-O-benzyl-6-deoxy-alpha-L-galactopyranosyl)-alpha-D-glucopyranoside DTXSID90747098 (C46H53NO12) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
