Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)ethyl)-6-hydroxy-1,3-dioxooctahydro-1H-4,7-methanoisoindole-5-carbonitrile.
2-(2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)ethyl)-6-hydroxy-1,3-dioxooctahydro-1H-4,7-methanoisoindole-5-carbonitrile (CAS 321998-81-6), molecular formula C18H16ClF3N4O3 and molecular weight 428.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)ethyl)-6-hydroxy-1,3-dioxooctahydro-1H-4,7-methanoisoindole-5-carbonitrile (C18H16ClF3N4O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-(2-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)ethyl)-6-hydroxy-1,3-dioxooctahydro-1H-4,7-methanoisoindole-5-carbonitrile 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.
