2,4-Dihydroxybenzophenone(Cas 131-56-6) Usage

Preparation

Obtained by condensation of benzanilide with resorcinol in the presence of zinc chloride and phosphorous oxychloride at 130–140° for 1 h (25%).

Contact allergens

BZP-1 is used, for example, in paints, plastics, and nail varnishes.

Safety Profile

Poison by intravenous and intraperitoneal routes. Mildly toxic by ingestion. An eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Recrystallise it from MeOH. [Beilstein 8 IV 2442.]
