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.
Tributyl(octyl)phosphonium chloride (CAS 56315-19-6), molecular formula C20H44PCl and molecular weight 351.00 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tributyl(octyl)phosphonium chloride (C20H44PCl) contains organophosphorus functionality, chlorine 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 351.00 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.
