Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(4-Chlorophenyl)-4,5-dihydroisoxazole-5-carbonitrile (CAS 1173119-75-9), molecular formula C10H7ClN2O and molecular weight 206.63 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Chlorophenyl)-4,5-dihydroisoxazole-5-carbonitrile (C10H7ClN2O) 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).
As a certified reference material (CRM), 3-(4-Chlorophenyl)-4,5-dihydroisoxazole-5-carbonitrile 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.
