Chemical Structure
Description
The occurrence of (1,2-Phenylenebis(methylene))bis(triphenylphosphonium) is closely related to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(1,2-Phenylenebis(methylene))bis(triphenylphosphonium) (CAS 47861-42-7), molecular formula C44H38P2Cl and molecular weight 664.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system, (1,2-Phenylenebis(methylene))bis(triphenylphosphonium) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 664.19 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (1,2-Phenylenebis(methylene))bis(triphenylphosphonium) 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.
