Chemical Structure
Description
The occurrence of Beta-D-Glucosamine is closely related to a carbohydrate-derived structure, an amide group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Beta-D-Glucosamine (CAS 14257-69-3), a certified reference material (molecular formula C6H13NO5HCl, MW 215.63 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, an amide group, chlorine substitution, Beta-D-Glucosamine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Beta-D-Glucosamine 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.
