Chemical Structure
Description
The molecular framework of ((1,3-Dioxan-2-yl)methyl)triphenylphosphonium bromide (C23H24O2PBr) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
((1,3-Dioxan-2-yl)methyl)triphenylphosphonium bromide (CAS 73022-37-4) is a high-purity analytical reference standard with the molecular formula C23H24O2PBr and a molecular weight of 443.32 g/mol.
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.
