Description
CATO supplies 2-(1-Chloroethyl)-5-(3,4-dimethylphenyl)-1,3,4-oxadiazole (CAS 1156945-18-4), a certified reference material (molecular formula C12H13ClN2O, MW 236.70 g/mol) for analytical method development and quality control.
2-(1-Chloroethyl)-5-(3,4-dimethylphenyl)-1,3,4-oxadiazole (C12H13ClN2O) 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(1-Chloroethyl)-5-(3,4-dimethylphenyl)-1,3,4-oxadiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
