Chemical Structure
Description
As a certified reference material (CRM), 2-(2,3-Dihydro-1h-1,3-benzodiazol-2-ylidene)-3-oxobutanenitrile 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.
2-(2,3-Dihydro-1h-1,3-benzodiazol-2-ylidene)-3-oxobutanenitrile (CAS 301344-08-1), molecular formula C11H9N3O and molecular weight 199.21 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2,3-Dihydro-1h-1,3-benzodiazol-2-ylidene)-3-oxobutanenitrile (C11H9N3O) 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; 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
