d-Methamphetamine is 170-175 oC at ~95% purity. At 98% purity melting point is 174-175 oC.
Mixtures of the d & l isomers have different melting points to a single pure isomer.
Phenylisopropylmethylamine hydrochloride ; C10H15N.HCl C6H5CH2CH(NHCH3)CH3.HCl reacts with HgCl2, and Phenylisopropylmethylamine freebase reacts with HAuCl4, and H2PtCl6 to form a precipitate metallic salt with characteristic melting point and crystal properties.
