Chemical Structure
Description
The occurrence of ((Diphenylphosphino)ethynyl)diphenylphosphine 5112-95-8 Bis(diphenylphosphino)acetylene Bis(diphenylphosphino)ethyne is closely related to organophosphorus functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
((Diphenylphosphino)ethynyl)diphenylphosphine 5112-95-8 Bis(diphenylphosphino)acetylene Bis(diphenylphosphino)ethyne (CAS 5112-95-8) is a high-purity analytical reference standard with the molecular formula C26H44P2 and a molecular weight of 418.58 g/mol.
((Diphenylphosphino)ethynyl)diphenylphosphine 5112-95-8 Bis(diphenylphosphino)acetylene Bis(diphenylphosphino)ethyne (C26H44P2) contains organophosphorus functionality, an aromatic ring 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures ((Diphenylphosphino)ethynyl)diphenylphosphine 5112-95-8 Bis(diphenylphosphino)acetylene Bis(diphenylphosphino)ethyne under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
