Chemical Structure
Description
Structurally, N-[2,3-Dihydro-1,3-dioxo-2-(2-pyridinyl)-1H-benz[de]isoquinolin-6-yl]acetamide (C27H42O5) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 446.62 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).
N-[2,3-Dihydro-1,3-dioxo-2-(2-pyridinyl)-1H-benz[de]isoquinolin-6-yl]acetamide (CAS 4931-97-9), molecular formula C27H42O5 and molecular weight 446.62 g/mol, is a CATO reference standard with documented purity and traceability.
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.
