Description

The occurrence of 2-(4-Bromobenzenesulfinyl)-1,1-diphenylethan-1-ol is closely related to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(4-Bromobenzenesulfinyl)-1,1-diphenylethan-1-ol (CAS 251307-38-7) is a high-purity analytical reference standard with the molecular formula C20H17BrO2S and a molecular weight of 401.32 g/mol.

Structurally, 2-(4-Bromobenzenesulfinyl)-1,1-diphenylethan-1-ol (C20H17BrO2S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, bromine 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 401.32 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 2-(4-Bromobenzenesulfinyl)-1,1-diphenylethan-1-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
