Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-3-phenylsulfonamidopyridine-5-boronic acid pinacol ester, 97%.
CATO supplies 2-Chloro-3-phenylsulfonamidopyridine-5-boronic acid pinacol ester, 97% (CAS 1083326-55-9), a certified reference material (molecular formula C17H20BClN2O4S, MW 394.68 g/mol) for analytical method development and quality control.
2-Chloro-3-phenylsulfonamidopyridine-5-boronic acid pinacol ester, 97% (C17H20BClN2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. 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 2-Chloro-3-phenylsulfonamidopyridine-5-boronic acid pinacol ester, 97% 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.
