Chemical Structure

1,3-Bis(di-i-propylphosphino)propane, min. 98% (dippp) CAS 91159-11-4 chemical structure

Description

CATO supplies 1,3-Bis(di-i-propylphosphino)propane, min. 98% (dippp) (CAS 91159-11-4), a certified reference material (molecular formula C15H34P2, MW 276.38 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H34P2, 1,3-Bis(di-i-propylphosphino)propane, min. 98% (dippp) contains organophosphorus functionality; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 276.38 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.

As a certified reference material (CRM), 1,3-Bis(di-i-propylphosphino)propane, min. 98% (dippp) 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.
