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.
Benzyltributylphosphonium chloride (CAS 1224-56-2), molecular formula C19H34PCl and molecular weight 328.90 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, chlorine substitution, Benzyltributylphosphonium chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
