Chemical Structure

Glucosamine sulfate impurity 23 CAS 1136-44-3 chemical structure

Description

Based on its molecular formula C8H15NO6, Glucosamine sulfate impurity 23 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 221.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies Glucosamine sulfate impurity 23 (CAS 1136-44-3), a pharmacopoeial impurity reference standard (molecular formula C8H15NO6, MW 221.21 g/mol) used for the identification and quantification of trace impurities in APIs.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Glucosamine sulfate impurity 23 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
