4'-Bromo-3-(methylsulfonyl)-1,1'-biphenyl CAS 904086-03-9

Description

The occurrence of 4'-Bromo-3-(methylsulfonyl)-1,1'-biphenyl is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4'-Bromo-3-(methylsulfonyl)-1,1'-biphenyl (CAS 904086-03-9), molecular formula C13H11BrO2S and molecular weight 311.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4'-Bromo-3-(methylsulfonyl)-1,1'-biphenyl (C13H11BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 311.19 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
