An improved test for cocaine, methaqualone and methadone with a modified cobalt(II) thiocyanate reagent
ANALYSTANALYST Pub Date: DOI: 10.1039/AN9729700263
Abstract
The classical cobalt(II) thiocyanate reagent has been rendered more sensitive and selective so as to provide a convenient field test for cocaine, methaqualone and methadone, substances that fail to give clear positive responses in the widely used Marquis procedure.
