Chemical Structure

Vitamin B6 (Pyridoxine) Impurity 40 HCl CAS 875-26-3 chemical structure

Description

The occurrence of Vitamin B6 (Pyridoxine) Impurity 40 HCl is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Vitamin B6 (Pyridoxine) Impurity 40 HCl (CAS 875-26-3), a pharmacopoeial impurity reference standard (molecular formula C8H11NO2HCl, MW 189.64 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Vitamin B6 (Pyridoxine) Impurity 40 HCl (C8H11NO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 189.64 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Vitamin B6 (Pyridoxine) Impurity 40 HCl 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.
