Chemical Structure
Description
Tributyl(octadecyl)phosphonium bromide (CAS 14866-42-3), molecular formula C30H64PBr and molecular weight 535.72 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tributyl(octadecyl)phosphonium bromide (C30H64PBr) contains organophosphorus functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 535.72 g/mol, it falls into the moderately-high-molecular-weight range. 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.
