Dihexylphosphinic acid CAS 7646-81-3

Description

Compared with other compounds in its class, the molecular weight of 234.32 g/mol gives Dihexylphosphinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Dihexylphosphinic acid (CAS 7646-81-3), a certified reference material (molecular formula C12H27O2P, MW 234.32 g/mol) for analytical method development and quality control.

The molecular framework of Dihexylphosphinic acid (C12H27O2P) is characterized by organophosphorus functionality, 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), Dihexylphosphinic acid 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.
