Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4-Methylumbelliferyl 3-4-6-tri-O-acetyl-2-azido-2-deoxy-α-D-galactopyranoside is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 489.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
4-Methylumbelliferyl 3-4-6-tri-O-acetyl-2-azido-2-deoxy-α-D-galactopyranoside (CAS 124167-43-7) is a high-purity analytical reference standard with the molecular formula C22H23N3O10 and a molecular weight of 489.43 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
