Abstract

A method of assaying primary amines or cyanide is disclosed. The process is carried out by reacting a substituted or unsubstituted naphthalene-2,3-dicarboxaldehyde or o-phthalaldehyde, reactive with primary amines and cyanide, with cyanide ions and at least one primary amine to form an adduct amenable to fluorometric or electrochemical assaying techniques. The adduct is then fluorometrically or electrochemically assayed. Also disclosed are 1-cyano-benz[f]isoindole adducts.
