Chemical Structure
Description
CATO supplies (4-Methylphenylboronic acid pinacol ester) triphenylphosphine bromide (CAS 1169942-85-1), a certified reference material (molecular formula C31H57BO2PBr, MW 583.48 g/mol) for analytical method development and quality control.
Based on its molecular formula C31H57BO2PBr, (4-Methylphenylboronic acid pinacol ester) triphenylphosphine bromide contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 583.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), (4-Methylphenylboronic acid pinacol ester) triphenylphosphine bromide 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.
