Chemical Structure
Description
The occurrence of 1,4-Bis(bis(3,5-dimethylphenyl)phosphino)butane is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,4-Bis(bis(3,5-dimethylphenyl)phosphino)butane (CAS 220185-37-5) is a high-purity analytical reference standard with the molecular formula C36H44P2 and a molecular weight of 538.68 g/mol.
1,4-Bis(bis(3,5-dimethylphenyl)phosphino)butane (C36H44P2) contains organophosphorus functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1,4-Bis(bis(3,5-dimethylphenyl)phosphino)butane 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.
