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 4-Iodo-1h,3h-thieno[3,4-c]furan-1,3-dione.
4-Iodo-1h,3h-thieno[3,4-c]furan-1,3-dione (CAS 2222337-05-3), molecular formula C6HIO3S and molecular weight 280.04 g/mol, is a CATO reference standard with documented purity and traceability.
4-Iodo-1h,3h-thieno[3,4-c]furan-1,3-dione (C6HIO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 4-Iodo-1h,3h-thieno[3,4-c]furan-1,3-dione 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.
