3-(2-Chlorophenyl)-4-(5-ethoxy-1,3-oxazol-2-yl)-5-methyl-1,2-oxazole CAS 338965-30-3

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(2-Chlorophenyl)-4-(5-ethoxy-1,3-oxazol-2-yl)-5-methyl-1,2-oxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

3-(2-Chlorophenyl)-4-(5-ethoxy-1,3-oxazol-2-yl)-5-methyl-1,2-oxazole (CAS 338965-30-3), molecular formula C15H13ClN2O3 and molecular weight 304.73 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
