Storage method

This product should be kept sealed.

Synthesis method

P-chlorobenzenesulfonylpropionamide sodium salt is obtained by reacting p-chlorobenzenesulfonamide and butanamide. Then acidify and refine with hydrochloric acid to obtain the finished product. Another method is to use p-chlorobenzenesulfonamide, propyl isocyanate, and triethylamine as raw materials.

Purpose

UV absorber. Mainly used in sunscreen and tanning cosmetics, it is chemically stable to light and air, safe for the skin, and has the ability to form a film on the skin. Can effectively absorb U. V． B area 280-320μm medium wave light area) ultraviolet light. The added amount is usually about 4%.

Sulfonylureas are oral hypoglycemic drugs. It has a strong and long-lasting effect, mainly selectively acting on pancreatic islet-β-cells, promoting the secretion of pancreatic islets and lowering blood sugar. Used for diabetes. Chlorpropamide has relatively serious side effects, so the use of this drug has been decreasing year by year.
