2-Acetamido-2-deoxy-3-O-(β-D-2-acetamido-2-deoxyglucopyranosyl)-D-galactopyranose CAS 95673-98-6

Description

The occurrence of 2-Acetamido-2-deoxy-3-O-(β-D-2-acetamido-2-deoxyglucopyranosyl)-D-galactopyranose is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Acetamido-2-deoxy-3-O-(β-D-2-acetamido-2-deoxyglucopyranosyl)-D-galactopyranose (CAS 95673-98-6), molecular formula C16H28N2O11 and molecular weight 424.40 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Acetamido-2-deoxy-3-O-(β-D-2-acetamido-2-deoxyglucopyranosyl)-D-galactopyranose (C16H28N2O11) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
