7-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)-N-(2,2,2-trichloro-1-hydroxyethyl)heptanamide (CAS 1803571-70-1), molecular formula C17H19Cl3N2O4 and molecular weight 421.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)-N-(2,2,2-trichloro-1-hydroxyethyl)heptanamide (C17H19Cl3N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 421.70 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.
