Chemical Structure

Allyltributylphosphonium bromide CAS 55894-18-3 chemical structure

Description

Allyltributylphosphonium bromide (CAS 55894-18-3), molecular formula C15H32PBr and molecular weight 323.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Allyltributylphosphonium bromide (C15H32PBr) contains organophosphorus functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 323.30 g/mol, it falls into the moderately-high-molecular-weight range. 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.

As a certified reference material (CRM), Allyltributylphosphonium bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
