Applications & Uses

Uses

5-Bromosalicylic Acid is a derivative of Salicylic Acid (S088125) and exhibits antiinflammatory activity.

Uses

5-Bromosalicylic acid may be employed as a starting reagent for the synthesis of honokiol, a biphenyl-type neolignan.

General Description

5-Bromosalicylic acid is a salicylic acid derivative. Its bonding to viscose fabric can impart antibacterial properties to the fabric. It has been identified as one of the brominated disinfection byproduct (Br-DBP) formed during the chlorination of saline sewage effluents.
