Purpose:
As an important organic synthesis intermediate, it is widely used in fields such as pharmaceuticals, fragrances, dyes, pesticides, etc.
? Used for synthesizing pharmaceuticals such as sulfamethoxazole, barbiturates, chloroquine, prednisone, norfloxacin, etc.
? It can be used as an intermediate of spices, and can be used to prepare pear, apple, grape and other fruit essence, and is allowed to be used as food spices.
? Used for the production of sulfonylurea herbicides (such as bensulfuron methyl and pyrimethanil) as well as dyes and pigments (such as benzimidazolones).
Can be used as a solvent and plasticizer for resins and nitrocellulose, as well as a diluent for coatings and adhesives.
Used in analytical chemistry for detecting ammonia and potassium, and can also be used as a gas chromatography stationary phase
