Chemical Structure

1,2-Bis(di-tert-butylphosphino)ethane CAS 107783-62-0 chemical structure

Description

Based on its molecular formula C18H40P2, 1,2-Bis(di-tert-butylphosphino)ethane contains organophosphorus functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 318.46 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.

CATO supplies 1,2-Bis(di-tert-butylphosphino)ethane (CAS 107783-62-0), a certified reference material (molecular formula C18H40P2, MW 318.46 g/mol) for analytical method development and quality control.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
