Chemical Structure
Description
Structurally, 3-(4-Ethylphenyl)-6-methyl-3,4-dihydro-2H-benzo[b][1,4]oxazine (C17H19NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 253.34 g/mol, it falls into the medium-molecular-weight range. 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).
3-(4-Ethylphenyl)-6-methyl-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 1713588-30-7) is a high-purity analytical reference standard with the molecular formula C17H19NO and a molecular weight of 253.34 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
