Field test for methaqualone and mecloqualone

摘要

A method for indicating the presence of methaqualone and/or mecloqualone is disclosed comprising the steps of adding seven drops of 85% solution of formic acid to the substance suspected of containing methaqualone or mecloqualone. Thereafter, adding five drops of five percent aqueous solution of sodium nitrite, and six to ten drops of chloroform. A positive indication of the presence of methaqualone or mecloqualone results in a yellow color in the chloroform and a clear water-white color in the aqueous solution.
