The occurrence of (3,5-Di-tert-butyl-4-hydroxybenzyl)triphenylphosphonium bromide is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3,5-Di-tert-butyl-4-hydroxybenzyl)triphenylphosphonium bromide (CAS 62546-89-8) is a high-purity analytical reference standard with the molecular formula C33H38OPBr and a molecular weight of 561.54 g/mol.
Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, (3,5-Di-tert-butyl-4-hydroxybenzyl)triphenylphosphonium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 561.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), (3,5-Di-tert-butyl-4-hydroxybenzyl)triphenylphosphonium 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.
