Chemical Structure

Phosphoric acid, diiSodecyl phenyl ester CAS 51363-64-5 chemical structure

Description

The molecular framework of Phosphoric acid, diiSodecyl phenyl ester (C26H47O4P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Phosphoric acid, diiSodecyl phenyl ester (CAS 51363-64-5) is a high-purity analytical reference standard with the molecular formula C26H47O4P and a molecular weight of 454.62 g/mol.

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.
