Tri-n-octyl phosphate (see also 9489.24) CAS 1806-54-8

Description

Compared with other compounds in its class, the molecular weight of 434.63 g/mol gives Tri-n-octyl phosphate (see also 9489.24) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tri-n-octyl phosphate (see also 9489.24) (CAS 1806-54-8) is a high-purity analytical reference standard with the molecular formula C24H51O4P and a molecular weight of 434.63 g/mol.

The molecular framework of Tri-n-octyl phosphate (see also 9489.24) (C24H51O4P) 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 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), Tri-n-octyl phosphate (see also 9489.24) 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.
