Chemical Structure
Description
The occurrence of Glucosamine sulfate impurity 18 is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Glucosamine sulfate impurity 18 (CAS CATO-C4X-194618), a pharmacopoeial impurity reference standard (molecular formula C6H13NO5, MW 179.17 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C6H13NO5, Glucosamine sulfate impurity 18 contains a carbohydrate-derived structure, an amide group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 179.17 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.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Glucosamine sulfate impurity 18 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.
