Chemical Structure
Description
The occurrence of Pyridoxine Trimer(Vitamin B6 Impurity 52) trihydrochloride is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Pyridoxine Trimer(Vitamin B6 Impurity 52) trihydrochloride (CAS 78761-51-0(Free Base)) is a certified pharmaceutical impurity reference standard with the molecular formula C24H29N3O7HCl and a molecular weight of 507.97 g/mol.
The molecular framework of Pyridoxine Trimer(Vitamin B6 Impurity 52) trihydrochloride (C24H29N3O7HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures Pyridoxine Trimer(Vitamin B6 Impurity 52) trihydrochloride 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.
