4-(carboxymethyl)thiophene-3-carboxylic acid CAS 57279-54-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(carboxymethyl)thiophene-3-carboxylic acid.

CATO supplies 4-(carboxymethyl)thiophene-3-carboxylic acid (CAS 57279-54-6), a certified reference material (molecular formula C7H6O4S, MW 186.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H6O4S, 4-(carboxymethyl)thiophene-3-carboxylic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 4-(carboxymethyl)thiophene-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
