CATO supplies 1-[4-[[2,3-Dihydro-3-(phenylmethylene)-1H-cyclopenta[b]quinolin-9-yl]carbonyl]-1-piperazinyl]ethanone (CAS 1090542-32-7), a certified reference material (molecular formula C26H25N3O2, MW 411.50 g/mol) for analytical method development and quality control.
Structurally, 1-[4-[[2,3-Dihydro-3-(phenylmethylene)-1H-cyclopenta[b]quinolin-9-yl]carbonyl]-1-piperazinyl]ethanone (C26H25N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 411.50 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.
