Chemical Structure
Description
Vitamin B6 (Pyridoxine) Impurity 42 (CAS CATO-C4X-187742) is a certified pharmaceutical impurity reference standard with the molecular formula C14H21NO3HCl and a molecular weight of 287.78 g/mol.
The molecular framework of Vitamin B6 (Pyridoxine) Impurity 42 (C14H21NO3HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
