Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Fluoro-4'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-4-ol (CAS 1261943-93-4), molecular formula C16H16FNO3S and molecular weight 321.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Fluoro-4'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-4-ol (C16H16FNO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 2-Fluoro-4'-(pyrrolidin-1-ylsulfonyl)-[1,1'-biphenyl]-4-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
