Microcrystalloscopic Differentiation of 3,4-Methylenedioxyamphetamine and Related Amphetamine Derivatives
Commonly used gold chloride and its diluted forms are compared with gold bromide for potential microcrystalloscopic differentiation of 3,4-methylenedioxyamphetamine (MDA) and related amphetamine derivatives. The crystal formation characteristics of MDA, mescaline, and 2,5-dimethoxy-4-ethylamphetamine (DOET) with diluted and undiluted gold chloride allow differentiation of these drugs, while 3,4-methylenedioxymethamphetamine (MDMA) and 3,4-methylenedioxy-N-ethylamphetamine (MDEA) form similar crystals and are not easily differentiated. The compounds 2,5-dimethoxy-4-methylamphetamine (DOM) and N-hydroxy-MDA were soluble in the gold chloride reagents, and no crystals were formed.
