For this third paper in a series reporting the results of analyses of illicit methamphetamine preparations [1,2], exhibits of dl-methamphetamine hydrochloride (I) appearing as off-white blocks or hygroscopic powder were examined and found to contain substantial quantities of methylamine hydrochloride (II). Some of the powder exhibits contained, as diluents, mannitol (III), dextrose (IV), or a combination of one of these with magnesium sulfate. Examination for other impurities indicated only traces, at most, of unidentifiable compounds.
