Chemical Structure
Description
As a certified reference material (CRM), 3- (Bromomethyl) phenyl boronic acid 3-(bromomethyl)phenylboronic acid 51323-43-4 A22560 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.
3- (Bromomethyl) phenyl boronic acid 3-(bromomethyl)phenylboronic acid 51323-43-4 A22560 (CAS 51323-43-4) is a high-purity analytical reference standard with the molecular formula C7H14BBrO2 and a molecular weight of 220.90 g/mol.
3- (Bromomethyl) phenyl boronic acid 3-(bromomethyl)phenylboronic acid 51323-43-4 A22560 (C7H14BBrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
