Microcrystalline Identification of Drugs of Abuse: The “White Cross Suite”
The microcrystallographic properties of the diliturate (5-nitrobarbituric acid) derivatives of the amine drugs found in the illicit street drug preparations known as “white crosses” have been determined. The crystallographic properties, such as the crystal morphology, the extinction angles, the sign of elongation, and front face refractive indices serve to identify the drugs found in the illicit preparations. These data can be used with ultraviolet and infrared spectroscopic and chromatographic evaluations as a major method for the identification of drugs of abuse.
