Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((4-Carboxythiophen-3-yl)carbamoyl)thiophene-3-carboxylic acid.
2-((4-Carboxythiophen-3-yl)carbamoyl)thiophene-3-carboxylic acid (CAS 90312-12-2) is a high-purity analytical reference standard with the molecular formula C6H7NO3S and a molecular weight of 173.19 g/mol.
Structurally, 2-((4-Carboxythiophen-3-yl)carbamoyl)thiophene-3-carboxylic acid (C6H7NO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 173.19 g/mol, it falls into the medium-molecular-weight range. 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.
