Chemical Structure

4-Benzyl-4h-thieno[3,2-b]pyrrole-5-carboxylic acid CAS 837390-55-3 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-Benzyl-4h-thieno[3,2-b]pyrrole-5-carboxylic acid (CAS 837390-55-3) is a high-purity analytical reference standard with the molecular formula C14H11NO2S and a molecular weight of 257.31 g/mol.

The molecular framework of 4-Benzyl-4h-thieno[3,2-b]pyrrole-5-carboxylic acid (C14H11NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 4-Benzyl-4h-thieno[3,2-b]pyrrole-5-carboxylic 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.
