Chemical Structure
Description
CATO supplies (5-(2-Methoxyphenyl)thiophen-2-yl)boronic acid (CAS 2225169-64-0), a certified reference material (molecular formula C11H11BO3S, MW 234.08 g/mol) for analytical method development and quality control.
(5-(2-Methoxyphenyl)thiophen-2-yl)boronic acid (C11H11BO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures (5-(2-Methoxyphenyl)thiophen-2-yl)boronic 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.
