Chemical Structure
Description
The occurrence of Ethyl-2,2,2-d3-triphenylphosphonium Bromide is closely related to deuterium isotope labeling, organophosphorus functionality, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl-2,2,2-d3-triphenylphosphonium Bromide (CAS 1560-55-0) is a high-purity analytical reference standard with the molecular formula C20H17D3PBr and a molecular weight of 374.28 g/mol.
The molecular framework of Ethyl-2,2,2-d3-triphenylphosphonium Bromide (C20H17D3PBr) is characterized by deuterium isotope labeling, organophosphorus functionality, bromine substitution, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
