Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9-(4-Chlorophenyl)-2,4-bis(trifluoromethyl)-[1,2,4]triazolo[4,3-a]1,8-naphthyridine.
9-(4-Chlorophenyl)-2,4-bis(trifluoromethyl)-[1,2,4]triazolo[4,3-a]1,8-naphthyridine (CAS 338773-24-3) is a high-purity analytical reference standard with the molecular formula C17H7ClF6N4 and a molecular weight of 416.71 g/mol.
The molecular framework of 9-(4-Chlorophenyl)-2,4-bis(trifluoromethyl)-[1,2,4]triazolo[4,3-a]1,8-naphthyridine (C17H7ClF6N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 9-(4-Chlorophenyl)-2,4-bis(trifluoromethyl)-[1,2,4]triazolo[4,3-a]1,8-naphthyridine 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.
