Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 337.82 g/mol gives 4-Chloro-3'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-3-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Chloro-3'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-3-ol (CAS 1261922-65-9), a certified reference material (molecular formula C16H16ClNO3S, MW 337.82 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-3'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-3-ol (C16H16ClNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
