Description

Compared with other compounds in its class, the molecular weight of 329.39 g/mol gives 4-(4-Methylbenzoyl)-3-phenyl-3,4-dihydro-2H-1,4-benzoxazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(4-Methylbenzoyl)-3-phenyl-3,4-dihydro-2H-1,4-benzoxazine (CAS 338747-79-8) is a high-purity analytical reference standard with the molecular formula C22H19NO2 and a molecular weight of 329.39 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(4-Methylbenzoyl)-3-phenyl-3,4-dihydro-2H-1,4-benzoxazine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
