Compared with other compounds in its class, the molecular weight of 497.39 g/mol gives (2-(5-Carboxythiophen-2-yl)ethyl)triphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (2-(5-Carboxythiophen-2-yl)ethyl)triphenylphosphonium bromide (CAS 1174131-47-5), a certified reference material (molecular formula C25H22O2PSBr, MW 497.39 g/mol) for analytical method development and quality control.
Owing to a steroid core, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, (2-(5-Carboxythiophen-2-yl)ethyl)triphenylphosphonium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 497.39 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.
