Thiamine Impurity 39 CAS 1697156-52-7 chemical structure

Description

CATO manufactures Thiamine Impurity 39 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.

Thiamine Impurity 39 (CAS 1697156-52-7) is a certified pharmaceutical impurity reference standard with the molecular formula C10H18N4 and a molecular weight of 194.28 g/mol.

The molecular framework of Thiamine Impurity 39 (C10H18N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
