Chemical Structure

Dalilesen Impurity 20 CAS CATO-C4X-301020 chemical structure

Description

CATO manufactures Dalilesen Impurity 20 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.

Dalilesen Impurity 20 (CAS CATO-C4X-301020) is a certified pharmaceutical impurity reference standard with the molecular formula C13H17N3 and a molecular weight of 215.29 g/mol.

The molecular framework of Dalilesen Impurity 20 (C13H17N3) 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.
