Description
CATO manufactures 3-Chlorothiophene-2,5-diboronic 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.
3-Chlorothiophene-2,5-diboronic acid (CAS 2096332-07-7) is a high-purity analytical reference standard with the molecular formula C4H5B2ClO4S and a molecular weight of 206.22 g/mol.
3-Chlorothiophene-2,5-diboronic acid (C4H5B2ClO4S) contains a carbohydrate-derived structure, a sulfone group, chlorine substitution. 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
