Description
CATO supplies 2-(3,4-Dichlorophenyl)-N-(5-methylisoxazol-3-yl)acetamide (CAS 916033-35-7), a certified reference material (molecular formula C12H10Cl2N2O2, MW 285.13 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H10Cl2N2O2, 2-(3,4-Dichlorophenyl)-N-(5-methylisoxazol-3-yl)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(3,4-Dichlorophenyl)-N-(5-methylisoxazol-3-yl)acetamide 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.
