Description
CATO supplies (E)-5-((2-chlorobenzyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carbaldehyde O-(2-chloroacetyl) oxime (CAS 321553-34-8), a certified reference material (molecular formula C15H12Cl2F3N3O2S, MW 426.24 g/mol) for analytical method development and quality control.
(E)-5-((2-chlorobenzyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carbaldehyde O-(2-chloroacetyl) oxime (C15H12Cl2F3N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 (E)-5-((2-chlorobenzyl)thio)-1-methyl-3-(trifluoromethyl)-1H-pyrazole-4-carbaldehyde O-(2-chloroacetyl) oxime 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.
