Hello, I am looking for Amin who has the appearance and characteristics of methamphetamine. Morpholine hydrochloride is good, but its color in the tube first turns yellow and then turns red. Methylamine hydrochloride is good too, but when it melts on aluminum foil, it decomposes the aluminum and catches fire. Friends and professors of chemistry, there is an amine similar to isopropylbenzylamine, please introduce it.
