Properties
Orthorhombic crystals, d 3.465. mp 506-509°; also reported as 488°: Bell, loc. cit. Sublimes at 473°. bp 520°. Very hygroscopic. Freely
sol in water. By saturating the concd viscous soln with HBr, the
tetrahydrate is formed. Sol in ethanol, in pyridine (185.6 g/l),
in ethyl bromide (1.0 g/l). Forms addition compounds with amines,
alcohols. Keep tightly closed.
