Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,6-dimethoxy-3-(trimethylsilyl)pyridine-5-boronic acid pinacol ester (CAS 2121513-69-5), molecular formula C16H28BNO4Si and molecular weight 337.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-dimethoxy-3-(trimethylsilyl)pyridine-5-boronic acid pinacol ester (C16H28BNO4Si) is characterized by an amide group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 2,6-dimethoxy-3-(trimethylsilyl)pyridine-5-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.
