3-PHENYLSALICYLIC ACID Usage And Synthesis

Uses

2''-Hydroxybiphenyl-3-carboxylic Acid can be used as antibacterial agents.

Safety Profile

Poison by intraperitoneal route. When heated to decomposition it emits acrid smoke and irritating fume

Purification Methods

Dissolve the acid in ca 1 equivalent of saturated aqueous Na2CO3, filter and precipitate it by adding 0.8 equivalents of M HCl. Crystallise it from ethylene dichloride (charcoal), and sublime it at 0.1mm. [Brooks et al. J Chem Soc 661 1961.]
