3,9-Dichloro-6-(9H-fluoren-2-yl)-5H-dibenzo[c,e]azepine-5,7(6H)-dione CAS 25698-59-3

Description

The occurrence of 3,9-Dichloro-6-(9H-fluoren-2-yl)-5H-dibenzo[c,e]azepine-5,7(6H)-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,9-Dichloro-6-(9H-fluoren-2-yl)-5H-dibenzo[c,e]azepine-5,7(6H)-dione (CAS 25698-59-3), molecular formula C27H15Cl2NO2 and molecular weight 456.32 g/mol, is a CATO reference standard with documented purity and traceability.

3,9-Dichloro-6-(9H-fluoren-2-yl)-5H-dibenzo[c,e]azepine-5,7(6H)-dione (C27H15Cl2NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.

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.
