Chemical Structure

Tetrakis(triphenylphosphite)nickel CAS 14221-00-2 chemical structure

Description

CATO supplies Tetrakis(triphenylphosphite)nickel (CAS 14221-00-2), a certified reference material (molecular formula C18H33O3PNi, MW 387.13 g/mol) for analytical method development and quality control.

Structurally, Tetrakis(triphenylphosphite)nickel (C18H33O3PNi) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 387.13 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
