(3-Hydroxybenzyl)triphenylphosphonium bromide CAS 74597-01-6

Description

Compared with other compounds in its class, the molecular weight of 449.33 g/mol gives (3-Hydroxybenzyl)triphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3-Hydroxybenzyl)triphenylphosphonium bromide (CAS 74597-01-6) is a high-purity analytical reference standard with the molecular formula C25H22OPBr and a molecular weight of 449.33 g/mol.

Based on its molecular formula C25H22OPBr, (3-Hydroxybenzyl)triphenylphosphonium bromide contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 449.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), (3-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.
