What is n-isopropylbenzylamine crystals?

N-isopropylbenzylamine (N-iso) is a synthetic crystalline substance that closely resembles methamphetamine in appearance, which has led to its use as a cutting agent for methamphetamine. The substance is highly soluble in water and has a melting point of approximately 200-205°C. N-iso is often identified by forensic laboratories and law enforcement agencies through chemical testing and spectroscopic analysis. The substance has been known to cause harmful physical effects, including respiratory distress, kidney damage, and cardiac arrest. Its use as a cutting agent for methamphetamine has been associated with an increased risk of overdose and other adverse health effects.
