Chemical Structure
Description
2-(Di-o-tolylphosphoryl)-N,N-diethylacetamide (CAS 101465-37-6) is a high-purity analytical reference standard with the molecular formula C20H26NO2P and a molecular weight of 343.40 g/mol.
The molecular framework of 2-(Di-o-tolylphosphoryl)-N,N-diethylacetamide (C20H26NO2P) is characterized by a steroid core, an amide group, organophosphorus functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 2-(Di-o-tolylphosphoryl)-N,N-diethylacetamide 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.
