Chemical Structure
Description
The occurrence of 3-Nitrothiophene-2-carboxylic acid is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Nitrothiophene-2-carboxylic acid (CAS 89283-80-7), molecular formula C5H3NO4S and molecular weight 173.15 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H3NO4S, 3-Nitrothiophene-2-carboxylic acid contains a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 173.15 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.
