1,2-Bis((S)-naphthalen-1-yl(phenyl)phosphanyl)ethane CAS 256469-70-2

Description

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.

1,2-Bis((S)-naphthalen-1-yl(phenyl)phosphanyl)ethane (CAS 256469-70-2), molecular formula C34H28P2 and molecular weight 498.53 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C34H28P2, 1,2-Bis((S)-naphthalen-1-yl(phenyl)phosphanyl)ethane contains organophosphorus functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 498.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 1,2-Bis((S)-naphthalen-1-yl(phenyl)phosphanyl)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.
