Chemical Structure

(-)-1,2-Bis[(2<I>R</I>,5<I>R</I>)-2,5-diethylphosphinealkyl]benzene CAS 136705-64-1 chemical structure

Description

CATO manufactures (-)-1,2-Bis[(2<I>R</I>,5<I>R</I>)-2,5-diethylphosphinealkyl]benzene 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.

(-)-1,2-Bis[(2<I>R</I>,5<I>R</I>)-2,5-diethylphosphinealkyl]benzene (CAS 136705-64-1) is a high-purity analytical reference standard with the molecular formula C22H42P2 and a molecular weight of 368.52 g/mol.

The molecular framework of (-)-1,2-Bis[(2<I>R</I>,5<I>R</I>)-2,5-diethylphosphinealkyl]benzene (C22H42P2) is characterized by organophosphorus functionality. 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.
