Chemical Structure

(+)-1,2-bis[(2<I>R</I>,5<I>R</I>)-2,5-diethylphosphinealkyl]ethane CAS 136705-62-9 chemical structure

Description

CATO manufactures (+)-1,2-bis[(2<I>R</I>,5<I>R</I>)-2,5-diethylphosphinealkyl]ethane 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]ethane (CAS 136705-62-9), molecular formula C18H36P2 and molecular weight 314.43 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (+)-1,2-bis[(2<I>R</I>,5<I>R</I>)-2,5-diethylphosphinealkyl]ethane (C18H36P2) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
