Chemical Structure
Description
CATO supplies 2-Bromo-butan-2-ylboronic acid pinacol ester (CAS 2379550-54-4), a certified reference material (molecular formula C10H20BBrO2, MW 262.98 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-butan-2-ylboronic acid pinacol ester (C10H20BBrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Bromo-butan-2-ylboronic acid pinacol ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
