Ethyl 5-butylthiophene-2-carboxylate CAS 2432848-93-4 chemical structure

Description

CATO manufactures Ethyl 5-butylthiophene-2-carboxylate 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.

CATO supplies Ethyl 5-butylthiophene-2-carboxylate (CAS 2432848-93-4), a certified reference material (molecular formula C11H16O2S, MW 212.31 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 5-butylthiophene-2-carboxylate (C11H16O2S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
