Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,3-Dichloro-5-(trifluoromethyl)isonicotinic acid (CAS 1135283-33-8), a certified reference material (molecular formula C7H2Cl2F3NO2, MW 260.00 g/mol) for analytical method development and quality control.
The molecular framework of 2,3-Dichloro-5-(trifluoromethyl)isonicotinic acid (C7H2Cl2F3NO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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.
CATO manufactures 2,3-Dichloro-5-(trifluoromethyl)isonicotinic acid 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.
