2,4-Dichloro-N-(4-{[(4-methylphenyl)sulfanyl]methyl}phenyl)benzamide CAS 338398-72-4

Description

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.

2,4-Dichloro-N-(4-{[(4-methylphenyl)sulfanyl]methyl}phenyl)benzamide (CAS 338398-72-4), molecular formula C21H17Cl2NOS and molecular weight 402.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,4-Dichloro-N-(4-{[(4-methylphenyl)sulfanyl]methyl}phenyl)benzamide (C21H17Cl2NOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 402.34 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).

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.
