Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 269.93 g/mol gives 3-Bromo-5-pyrrolidinophenylboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-5-pyrrolidinophenylboronic acid (CAS 1256355-16-4) is a high-purity analytical reference standard with the molecular formula C10H13BBrNO2 and a molecular weight of 269.93 g/mol.
3-Bromo-5-pyrrolidinophenylboronic acid (C10H13BBrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3-Bromo-5-pyrrolidinophenylboronic acid 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.
