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-(2,3-Dihydro-1,4-benzodioxin-6-yl)benzonitrile (CAS 893737-44-5), molecular formula C15H11NO2 and molecular weight 237.25 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2,3-Dihydro-1,4-benzodioxin-6-yl)benzonitrile (C15H11NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 3-(2,3-Dihydro-1,4-benzodioxin-6-yl)benzonitrile 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.
