p-Toluenesulfonamide

　　Uses

　　Industrial field: It is an excellent solid plasticizer for thermosetting plastics, suitable for resins such as phenolic resin, melamine resin, urea-formaldehyde resin, and polyamide. It can improve processability, ensure uniform curing, and impart good gloss to products. It can also be used in the production of synthetic resins and coatings; in coatings, it can improve performance, such as increasing gloss, hardness, and durability.

　　Pharmaceutical field: Used for the synthesis of drugs such as Chloramine-T and Sulfachloropyridazine, and can also serve as a pharmaceutical intermediate for the synthesis of other drugs.

　　Other aspects: It can be used to manufacture disinfectants, mildew inhibitors, and fungicides. In wood processing, it acts as a brightening agent, making the wood surface smoother and glossier. Additionally, it can be used to produce fluorescent dyes, saccharin, etc., and is commonly used as a nickel plating brightener to improve the coating structure, making the coating bright and uniform.
