Description
CATO supplies 2-(3,4-Dichlorophenyl)benzo[d]oxazole-5-carbaldehyde (CAS 1181377-98-9), a certified reference material (molecular formula C14H7Cl2NO2, MW 292.12 g/mol) for analytical method development and quality control.
2-(3,4-Dichlorophenyl)benzo[d]oxazole-5-carbaldehyde (C14H7Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 2-(3,4-Dichlorophenyl)benzo[d]oxazole-5-carbaldehyde 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.
