Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (2-Fluoro-4-(methoxycarbonyl)benzyl)triphenylphosphonium bromide (CAS 179252-79-0), a certified reference material (molecular formula C27H23FO2PBr, MW 509.35 g/mol) for analytical method development and quality control.
Structurally, (2-Fluoro-4-(methoxycarbonyl)benzyl)triphenylphosphonium bromide (C27H23FO2PBr) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 509.35 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
