Chemical Structure

(1,3-Propanedithiolate)(1,2-bis(diphenylphosphino)ethane)nickel(II) CAS 61703-81-9 chemical structure

Description

CATO supplies (1,3-Propanedithiolate)(1,2-bis(diphenylphosphino)ethane)nickel(II) (CAS 61703-81-9), a certified reference material (molecular formula C29H30NiP2S2, MW 563.32 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, organophosphorus functionality, a polycyclic aromatic system, (1,3-Propanedithiolate)(1,2-bis(diphenylphosphino)ethane)nickel(II) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 563.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
