Description

Compared with other compounds in its class, the molecular weight of 344.81 g/mol gives 4'-((4-Chlorophenyl)sulfonyl)-[1,1'-biphenyl]-4-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4'-((4-Chlorophenyl)sulfonyl)-[1,1'-biphenyl]-4-ol (CAS 30809-75-7), a certified reference material (molecular formula C18H13ClO3S, MW 344.81 g/mol) for analytical method development and quality control.

Structurally, 4'-((4-Chlorophenyl)sulfonyl)-[1,1'-biphenyl]-4-ol (C18H13ClO3S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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 344.81 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.
