Chemical Structure
Description
The occurrence of Methylenebis(triphenylphosphonium) bromide is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methylenebis(triphenylphosphonium) bromide (CAS 14529-09-0) is a high-purity analytical reference standard with the molecular formula C37H32P2 and a molecular weight of 538.60 g/mol.
Owing to organophosphorus functionality, a polycyclic aromatic system, Methylenebis(triphenylphosphonium) bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 538.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Methylenebis(triphenylphosphonium) 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.
