Amantadine hydrochloride, p-aminophenol hydrochloride, and methylamine hydrochloride, compounds often studied in pharmacology, were investigated by means of powder diffractometry. The chemical formula of the first compound is C10H17N HCl and crystallizes in the monoclinic system, space group C2∕c (15) with lattice parameters a=2.0279(6) nm, b=1.1171(2) nm, c=9.759(4) nm, and β=109.00(3)°. p-Aminophenol hydrochloride C6H7NO HCl crystallizes in the orthorhombic system, space group P222 with lattice parameters a=0.6619(2) nm, b=0.88461(2) nm, and c=0.6101(2) nm. Methylamine hydrochloride CH5N∙HCl crystallizes in the tetragonal system, space group P4∕nmm (129) with lattice parameters a=b=0.6068(1) nm and c=0.50689(8) nm.
