Chemical Structure
Description
2-(5-Methylthiophene-2-carbonyl)benzoic acid (CAS 152567-82-3) is a high-purity analytical reference standard with the molecular formula C13H10O3S and a molecular weight of 246.28 g/mol.
The molecular framework of 2-(5-Methylthiophene-2-carbonyl)benzoic acid (C13H10O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-(5-Methylthiophene-2-carbonyl)benzoic 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.
