Chemical Structure
Description
CATO supplies 4-Chloro-2-(trifluoromethyl)pyrido[2,3-d]pyrimidine (CAS 338739-98-3), a certified reference material (molecular formula C8H3ClF3N3, MW 233.58 g/mol) for analytical method development and quality control.
4-Chloro-2-(trifluoromethyl)pyrido[2,3-d]pyrimidine (C8H3ClF3N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 4-Chloro-2-(trifluoromethyl)pyrido[2,3-d]pyrimidine 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.
