Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 447.36 g/mol gives (2-Methylbenzyl)triphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(2-Methylbenzyl)triphenylphosphonium bromide (CAS 1530-36-5) is a high-purity analytical reference standard with the molecular formula C26H24PBr and a molecular weight of 447.36 g/mol.
Owing to organophosphorus functionality, bromine substitution, a polycyclic aromatic system, (2-Methylbenzyl)triphenylphosphonium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 447.36 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
