Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,6-Dibromothieno[3,4-b]thiophene-2-carboxylic acid.
4,6-Dibromothieno[3,4-b]thiophene-2-carboxylic acid (CAS 1024594-86-2) is a high-purity analytical reference standard with the molecular formula C7H2Br2O2S2 and a molecular weight of 342.03 g/mol.
4,6-Dibromothieno[3,4-b]thiophene-2-carboxylic acid (C7H2Br2O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 4,6-Dibromothieno[3,4-b]thiophene-2-carboxylic acid 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.
