Description

General description

Sodium salicylate can be prepared from the reaction of salicylic acid and ammonia. It exhibits fluorescence at higher concentrations and effectively absorbs β-particles. Due to these properties, it has been employed as fluor for the radioactivity detection in various gels.

Application

Sodium salicylate may be used as phenolic reagent in salicylate method for the determination of ammonia. It may be employed as a hydrotropic agent to study the release of anticancer drug camptothecin (CPT) from the mixed micelles [composed of Pluronic P105 (P105) and D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS)].
