overview | 2-hydroxybenzoic acid monoammonium salt is also called ammonium salicylate. Ammonium salicylate is an ammonium salt of salicylic acid that reacts with ammonia or ammonia to form an organic acid. It has good water solubility. The nature of ammonium salicylate is different from salicylic acid. It does not have sublimation and has certain high temperature resistance. Unlike salicylic acid, it will decarboxylate and decompose and produce phenol at high temperature. |
use | 2-hydroxybenzoic acid monoammonium salt is used as a pharmaceutical intermediate and an organic synthesis intermediate, mainly used in the laboratory research and development process and chemical medicine research and development process, and can be used to prepare o-hydroxybenzonitrile and salicylamide (salicylamide). |
