Chemical Structure
Description
The occurrence of 1,3-Bis[(di-tert-butylphosphino)oxy]benzene is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Bis[(di-tert-butylphosphino)oxy]benzene (CAS 338800-20-7) is a high-purity analytical reference standard with the molecular formula C22H40O2P2 and a molecular weight of 398.50 g/mol.
The molecular framework of 1,3-Bis[(di-tert-butylphosphino)oxy]benzene (C22H40O2P2) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
CATO manufactures 1,3-Bis[(di-tert-butylphosphino)oxy]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.
