Description
CATO supplies 5-(Methoxycarbonyl)-1-tosyl-1H-pyrrole-3-boronic Acid Pinacol Ester (CAS 869886-86-2), a certified reference material (molecular formula C19H24BNO6S, MW 405.27 g/mol) for analytical method development and quality control.
The molecular framework of 5-(Methoxycarbonyl)-1-tosyl-1H-pyrrole-3-boronic Acid Pinacol Ester (C19H24BNO6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-(Methoxycarbonyl)-1-tosyl-1H-pyrrole-3-boronic Acid Pinacol Ester 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.
