(11aR)-10,11,12,13-Tetrahydro-5-hydroxy-3,7-diphenyl-diindeno[7,1-de:1,7-fg][1,3,2]dioxaphosphocin (CAS 1297613-72-9), molecular formula C29H23O4P and molecular weight 466.46 g/mol, is a CATO reference standard with documented purity and traceability.

(11aR)-10,11,12,13-Tetrahydro-5-hydroxy-3,7-diphenyl-diindeno[7,1-de:1,7-fg][1,3,2]dioxaphosphocin (C29H23O4P) contains a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage. 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.

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.

As a certified reference material (CRM), (11aR)-10,11,12,13-Tetrahydro-5-hydroxy-3,7-diphenyl-diindeno[7,1-de:1,7-fg][1,3,2]dioxaphosphocin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
