Description
3,5-dimethyl-4-phenyl-1,2-oxazole (CAS 4345-46-4) is a high-purity analytical reference standard with the molecular formula C11H11NO and a molecular weight of 173.21 g/mol.
Based on its molecular formula C11H11NO, 3,5-dimethyl-4-phenyl-1,2-oxazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 173.21 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), 3,5-dimethyl-4-phenyl-1,2-oxazole 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.
