Bis(2-ethylhexyl) (2-ethylhexyl)phosphonate CAS 126-63-6

Description

Compared with other compounds in its class, the molecular weight of 418.63 g/mol gives Bis(2-ethylhexyl) (2-ethylhexyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bis(2-ethylhexyl) (2-ethylhexyl)phosphonate (CAS 126-63-6), a certified reference material (molecular formula C24H51O3P, MW 418.63 g/mol) for analytical method development and quality control.

Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, Bis(2-ethylhexyl) (2-ethylhexyl)phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Bis(2-ethylhexyl) (2-ethylhexyl)phosphonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
