2-(o-Tolyloxy)-4H-benzo[d][1,3,2]dioxaphosphinine 2-oxide CAS 1222-87-3

Description

2-(o-Tolyloxy)-4H-benzo[d][1,3,2]dioxaphosphinine 2-oxide (C14H13O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-(o-Tolyloxy)-4H-benzo[d][1,3,2]dioxaphosphinine 2-oxide (CAS 1222-87-3), molecular formula C14H13O4P and molecular weight 276.22 g/mol, is a CATO reference standard with documented purity and traceability.

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.
