Description
Compared with other compounds in its class, the molecular weight of 229.27 g/mol gives 1-(3-Mesitylisoxazol-5-yl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(3-Mesitylisoxazol-5-yl)ethanone (CAS 77987-98-5), molecular formula C14H15NO2 and molecular weight 229.27 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-Mesitylisoxazol-5-yl)ethanone (C14H15NO2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 1-(3-Mesitylisoxazol-5-yl)ethanone 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.
