Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(2,5-Dichlorophenyl)thiophene-2-carboxylic acid (CAS 1007089-03-3) is a high-purity analytical reference standard with the molecular formula C11H6Cl2O2S and a molecular weight of 273.14 g/mol.
5-(2,5-Dichlorophenyl)thiophene-2-carboxylic acid (C11H6Cl2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
CATO manufactures 5-(2,5-Dichlorophenyl)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.
