Silver oxide (Ag 2 O) was among the first reagents employed for this, [2] but a variety of other oxidising agents have been used successfully. [3] In solution, adrenochrome is pink and further oxidation of the compound causes it to polymerize into brown or black melanin compounds.
Adderall and Mydayis [11] are trade names [note 2] for a combination drug containing four salts of amphetamine.The mixture is composed of equal parts racemic amphetamine and dextroamphetamine, which produces a (3:1) ratio between dextroamphetamine and levoamphetamine, the two enantiomers of amphetamine.

3,5-dinitrobenzoic acid-2-propylester (mp.: 123 °C [4]). Compared to 4-nitrobenzoic acid , another acid that is used similarly, derivates of 3,5-dinitrobenzoic acid have higher melting points, so that it is preferred when the 4-nitrobenzoic acid derivate has a melting point too low to be accurately identified.
