Chemical Structure
Description
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.
2,5-dichlorothiophen-3-ylboronic acid (CAS 177735-28-3), molecular formula C4H7BCl2O2S and molecular weight 200.88 g/mol, is a CATO reference standard with documented purity and traceability.
2,5-dichlorothiophen-3-ylboronic acid (C4H7BCl2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
CATO manufactures 2,5-dichlorothiophen-3-ylboronic 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.
