5,8-Dichloro-7-hydroxy-3,4-dihydroisoquinolin-1(2H)-one CAS 1616289-20-3 chemical structure

Description

The occurrence of 5,8-Dichloro-7-hydroxy-3,4-dihydroisoquinolin-1(2H)-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5,8-Dichloro-7-hydroxy-3,4-dihydroisoquinolin-1(2H)-one (CAS 1616289-20-3) is a high-purity analytical reference standard with the molecular formula C9H7Cl2NO2 and a molecular weight of 232.06 g/mol.

Structurally, 5,8-Dichloro-7-hydroxy-3,4-dihydroisoquinolin-1(2H)-one (C9H7Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 232.06 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.
