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 5-Iodothiophene-3-carboxamide.
5-Iodothiophene-3-carboxamide (CAS 18800-08-3) is a high-purity analytical reference standard with the molecular formula C5H4INOS and a molecular weight of 253.06 g/mol.
Based on its molecular formula C5H4INOS, 5-Iodothiophene-3-carboxamide contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
