Chemical Structure
Description
2-(4-Ethoxyphenyl)-4,4-dimethyl-4,5-dihydrooxazole (C13H17NO2) 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).
2-(4-Ethoxyphenyl)-4,4-dimethyl-4,5-dihydrooxazole (CAS 180303-26-8), molecular formula C13H17NO2 and molecular weight 219.28 g/mol, is a CATO reference standard with documented purity and traceability.
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-(4-Ethoxyphenyl)-4,4-dimethyl-4,5-dihydrooxazole 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.
