Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-3-iodothiophene-2-carboxylic acid.
5-Bromo-3-iodothiophene-2-carboxylic acid (CAS 1389315-17-6) is a high-purity analytical reference standard with the molecular formula C5H2BrIO2S and a molecular weight of 332.94 g/mol.
5-Bromo-3-iodothiophene-2-carboxylic acid (C5H2BrIO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution. 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 5-Bromo-3-iodothiophene-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.
