Description
CATO manufactures 4-chloro-2-fluoropyrimidine 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.
CATO supplies 4-chloro-2-fluoropyrimidine (CAS 51422-00-5), a certified reference material (molecular formula C4H8ClFN2, MW 138.57 g/mol) for analytical method development and quality control.
4-chloro-2-fluoropyrimidine (C4H8ClFN2) contains 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.
