Chemical Structure
Description
1-Chloro-2-fluoro-5-nitronaphthalene (C10H5ClFNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
1-Chloro-2-fluoro-5-nitronaphthalene (CAS 2757096-67-4) is a high-purity analytical reference standard with the molecular formula C10H5ClFNO2 and a molecular weight of 225.60 g/mol.
