Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8,9,10,11-Tetrachloro-12H-phthaloperin-12-one.

8,9,10,11-Tetrachloro-12H-phthaloperin-12-one (CAS 20749-68-2) is a high-purity analytical reference standard with the molecular formula C18H6Cl4N2O and a molecular weight of 408.07 g/mol.

Structurally, 8,9,10,11-Tetrachloro-12H-phthaloperin-12-one (C18H6Cl4N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 408.07 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
