Chemical Structure
Description
Sodium 5-chlorothiophene-2-sulfinate (CAS 500708-75-8) is a high-purity analytical reference standard with the molecular formula C4H2ClO2S2Na and a molecular weight of 204.62 g/mol.
Based on its molecular formula C4H2ClO2S2Na, Sodium 5-chlorothiophene-2-sulfinate contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.62 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.
CATO manufactures Sodium 5-chlorothiophene-2-sulfinate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
