Chemical Structure
Description
The occurrence of 4-Phenyl-2-(thiophene-2-amido)thiophene-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Phenyl-2-(thiophene-2-amido)thiophene-3-carboxylic acid (CAS 342382-26-7) is a high-purity analytical reference standard with the molecular formula C16H11NO3S2 and a molecular weight of 329.39 g/mol.
The molecular framework of 4-Phenyl-2-(thiophene-2-amido)thiophene-3-carboxylic acid (C16H11NO3S2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
