Chemical Structure

Diisodecyl pentaerythritol diphosphite CAS 26544-27-4 chemical structure

Description

CATO supplies Diisodecyl pentaerythritol diphosphite (CAS 26544-27-4), a certified reference material (molecular formula C25H50O6P2, MW 508.61 g/mol) for analytical method development and quality control.

Structurally, Diisodecyl pentaerythritol diphosphite (C25H50O6P2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 508.61 g/mol, it falls into the moderately-high-molecular-weight range.

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.
