Chemical Structure
Description
7'-Bromo-2',3'-dihydro-1'h-spiro[cyclopropane-1,4'-isoquinoline] (C11H12BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
7'-Bromo-2',3'-dihydro-1'h-spiro[cyclopropane-1,4'-isoquinoline] (CAS 885269-31-8) is a high-purity analytical reference standard with the molecular formula C11H12BrN and a molecular weight of 238.12 g/mol.
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.
