Chemical Structure

N-acetyl-D-galactosamine-1- CAS 478518-53-5 chemical structure

Description

CATO manufactures N-acetyl-D-galactosamine-1- under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

N-acetyl-D-galactosamine-1- (CAS 478518-53-5) is a high-purity analytical reference standard with the molecular formula C7[13C]H15NO6 and a molecular weight of 222.20 g/mol.

The molecular framework of N-acetyl-D-galactosamine-1- (C7[13C]H15NO6) is characterized by an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
