Chemical Structure
Description
The occurrence of 9-Phenyl-2,3,3a,4-tetrahydro-1H-benzo[f]isoindol-1-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 9-Phenyl-2,3,3a,4-tetrahydro-1H-benzo[f]isoindol-1-one (CAS 59015-41-7), a certified reference material (molecular formula C18H15NO, MW 261.32 g/mol) for analytical method development and quality control.
Structurally, 9-Phenyl-2,3,3a,4-tetrahydro-1H-benzo[f]isoindol-1-one (C18H15NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 261.32 g/mol, it falls into the medium-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.
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.
