Description
CATO supplies 3-Methyl-4'-(methylsulfonyl)-[1,1'-biphenyl]-4-ol (CAS 1261895-23-1), a certified reference material (molecular formula C14H14O3S, MW 262.32 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methyl-4'-(methylsulfonyl)-[1,1'-biphenyl]-4-ol (C14H14O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
