4-Nitrophenyl 2-acetamido-2-deoxy-4-O-[2-O-(α-L-fucopyranosyl)-β-D-galactopyranosyl]-β-D-glucopyranoside CAS 177855-99-1

Description

4-Nitrophenyl 2-acetamido-2-deoxy-4-O-[2-O-(α-L-fucopyranosyl)-β-D-galactopyranosyl]-β-D-glucopyranoside (CAS 177855-99-1) is a high-purity analytical reference standard with the molecular formula C26H38N2O17 and a molecular weight of 650.58 g/mol.

4-Nitrophenyl 2-acetamido-2-deoxy-4-O-[2-O-(α-L-fucopyranosyl)-β-D-galactopyranosyl]-β-D-glucopyranoside (C26H38N2O17) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
