VitaminB6 Impurity C CAS CATO-CPS-2401002

Description

The occurrence of VitaminB6 Impurity C is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies VitaminB6 Impurity C (CAS CATO-CPS-2401002), a pharmacopoeial impurity reference standard (molecular formula C16H21N2O5HO, MW 338.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C16H21N2O5HO, VitaminB6 Impurity C contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 338.36 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.

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.

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.
