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 (Z)-[1-(Pyrazin-2-yl)ethylidene]amino 3-(2-chlorophenyl)-5-methyl-1,2-oxazole-4-carboxylate (CAS 866050-54-6), a certified reference material (molecular formula C17H13ClN4O3, MW 356.76 g/mol) for analytical method development and quality control.
(Z)-[1-(Pyrazin-2-yl)ethylidene]amino 3-(2-chlorophenyl)-5-methyl-1,2-oxazole-4-carboxylate (C17H13ClN4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures (Z)-[1-(Pyrazin-2-yl)ethylidene]amino 3-(2-chlorophenyl)-5-methyl-1,2-oxazole-4-carboxylate 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.
