Chemical Structure
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.
Diindeno[7,1-de:1′,7′-fg][1,3,2]dioxaphosphocin, 3,7-bis[3,5-bis(1,1-dimethylethyl)phenyl]-10,11,12,13-tetrahydro-5-hydroxy-, 5-oxide, (11aS)- (CAS 2280013-47-8), molecular formula C45H55O4P and molecular weight 690.89 g/mol, is a CATO reference standard with documented purity and traceability.
Diindeno[7,1-de:1′,7′-fg][1,3,2]dioxaphosphocin, 3,7-bis[3,5-bis(1,1-dimethylethyl)phenyl]-10,11,12,13-tetrahydro-5-hydroxy-, 5-oxide, (11aS)- (C45H55O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
