2-(Methylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid CAS 154117-62-1

Description

Compared with other compounds in its class, the molecular weight of 276.31 g/mol gives 2-(Methylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(Methylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid (CAS 154117-62-1), a certified reference material (molecular formula C14H12O4S, MW 276.31 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2-(Methylsulfonyl)-[1,1'-biphenyl]-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
