Chemical Structure

2-Bromophenylboronic acid mida ester CAS 943552-28-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 311.92 g/mol gives 2-Bromophenylboronic acid mida ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Bromophenylboronic acid mida ester (CAS 943552-28-1), molecular formula C11H11BBrNO4 and molecular weight 311.92 g/mol, is a CATO reference standard with documented purity and traceability.

2-Bromophenylboronic acid mida ester (C11H11BBrNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 2-Bromophenylboronic acid mida 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.
