2-(2,6-Diethylphenyl)-4-phenyloxazole-5-carbaldehyde CAS 832155-17-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2,6-Diethylphenyl)-4-phenyloxazole-5-carbaldehyde.

2-(2,6-Diethylphenyl)-4-phenyloxazole-5-carbaldehyde (CAS 832155-17-6), molecular formula C20H19NO2 and molecular weight 305.37 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(2,6-Diethylphenyl)-4-phenyloxazole-5-carbaldehyde (C20H19NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 305.37 g/mol, it falls into the moderately-high-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).

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.
