1(2H)-isoquinolinone, 4-bromo-7-methyl- (CAS 877263-69-9) is a high-purity analytical reference standard with the molecular formula C10H8BrNO and a molecular weight of 238.08 g/mol.
1(2H)-isoquinolinone, 4-bromo-7-methyl- (C10H8BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
