Chemical Structure

Glucosamine EP Impurity A CAS 72-87-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Glucosamine EP Impurity A.

Glucosamine EP Impurity A (CAS 72-87-7), molecular formula C9H16O6 and molecular weight 220.22 g/mol, is a CATO reference standard with documented purity and traceability.

Glucosamine EP Impurity A (C9H16O6) contains a carboxylic acid 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.

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.
