diphenyltolylphosphine CAS 1031-93-2 chemical structure

Description

CATO manufactures diphenyltolylphosphine 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.

diphenyltolylphosphine (CAS 1031-93-2) is a high-purity analytical reference standard with the molecular formula C19H35P and a molecular weight of 294.45 g/mol.

The molecular framework of diphenyltolylphosphine (C19H35P) 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.
