Chemical Structure
Description
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.
4-(5-Phenylthiophen-2-yl)butanoic acid (CAS 853921-26-3) is a high-purity analytical reference standard with the molecular formula C14H14O2S and a molecular weight of 246.32 g/mol.
The molecular framework of 4-(5-Phenylthiophen-2-yl)butanoic acid (C14H14O2S) 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).
CATO manufactures 4-(5-Phenylthiophen-2-yl)butanoic acid 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.
