Chemical Structure
Description
4-(2,2-Difluorocyclopropyl)aniline (C9H9F2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
4-(2,2-Difluorocyclopropyl)aniline (CAS 35694-68-9), molecular formula C9H9F2N and molecular weight 169.17 g/mol, is a CATO reference standard with documented purity and traceability.
