[(5-Chloro-1,3-benzoxazol-2-yl)sulfanyl](3-chlorophenyl)methanone CAS 338750-73-5

Description

Structurally, [(5-Chloro-1,3-benzoxazol-2-yl)sulfanyl](3-chlorophenyl)methanone (C14H7Cl2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 324.18 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).

[(5-Chloro-1,3-benzoxazol-2-yl)sulfanyl](3-chlorophenyl)methanone (CAS 338750-73-5), molecular formula C14H7Cl2NO2S and molecular weight 324.18 g/mol, is a CATO reference standard with documented purity and traceability.

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.
