Chemical Structure
Description
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.
4-(4-Chloro-phenyl)-3-chlorosulfonyl-5-trifluoro-methyl-thiophene-2-carboxylic acid methyl ester (CAS 1089330-66-4) is a high-purity analytical reference standard with the molecular formula C13H7Cl2F3O4S2 and a molecular weight of 419.22 g/mol.
The molecular framework of 4-(4-Chloro-phenyl)-3-chlorosulfonyl-5-trifluoro-methyl-thiophene-2-carboxylic acid methyl ester (C13H7Cl2F3O4S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 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 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.
