Is the chemical properties of 2-fluorobenzamine stable?

2-%E6%B0%9F%E8%8B%84%E8%83%BA, that is, 2-hydroxybenzoic acid, also known as salicylic acid. Its chemical properties are relatively stable.

Salicylic acid molecules contain carboxyl groups and phenolic hydroxyl groups, which are the key active sites. The presence of carboxyl groups at the ortho-position of phenolic hydroxyl groups makes phenolic hydroxyl hydrogens easier to dissociate, and the acidity is stronger than that of ordinary phenols. However, under normal circumstances, as long as it avoids contact with special chemicals such as strong oxidants and strong bases, it can maintain its own structural stability.

From the perspective of structure, the benzene ring conjugated system gives it a certain stability. The conjugated system makes the electron cloud uniformly distributed, reduces molecular energy and enhances stability. And the benzene ring is aromatic and is not prone to addition reactions. Under normal conditions, the structure of the benzene ring

Although salicylic acid is relatively stable, it will react under specific conditions due to the presence of active groups. For example, carboxyl groups can be esterified with alcohols under the catalysis of concentrated sulfuric acid to form salicylic acid esters; phenolic hydroxyl groups are easily oxidized, especially under the action of strong oxidants, phenolic hydroxyl groups may be oxidized to quinones and other substances. However, normal storage, such as in a cool, dry, ventilated place, to avoid light and moisture, salicylic acid can maintain chemical stability for a long time and does not easily deteriorate.

What are the synthesis methods of 2-fluorobenzyl amine?
