1,3-Bis(di-tert-butylphosphino)propane (CAS 121115-33-1) is a high-purity analytical reference standard with the molecular formula C19H42P2 and a molecular weight of 332.48 g/mol.
Based on its molecular formula C19H42P2, 1,3-Bis(di-tert-butylphosphino)propane contains organophosphorus functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 332.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
