Chemical Structure
Description
The occurrence of 4-bromanylbutyl(triphenyl)phosphanium bromide 4-bromobutyl(triphenyl)phosphonium bromide 7333-63-3 A837795 is closely related to organophosphorus functionality, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-bromanylbutyl(triphenyl)phosphanium bromide 4-bromobutyl(triphenyl)phosphonium bromide 7333-63-3 A837795 (CAS 7333-63-3), a certified reference material (molecular formula C22H41BrPBr, MW 496.35 g/mol) for analytical method development and quality control.
4-bromanylbutyl(triphenyl)phosphanium bromide 4-bromobutyl(triphenyl)phosphonium bromide 7333-63-3 A837795 (C22H41BrPBr) contains organophosphorus functionality, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
