Chemical Structure

Cyclopropyltriphenylphosphonium bromide CAS 14114-05-7 chemical structure

Description

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.

Cyclopropyltriphenylphosphonium bromide (CAS 14114-05-7), molecular formula C21H38PBr and molecular weight 401.41 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Cyclopropyltriphenylphosphonium bromide (C21H38PBr) contains organophosphorus functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 401.41 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.

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.
