N-n-Butyl benzene sulfonamide (CAS 3622-84-2) is a compound whose chemical structure dictates its valuable industrial applications, primarily as a plasticizer. Understanding its molecular makeup, physical properties, and synthesis methods is key to appreciating its role in enhancing materials. NINGBO INNO PHARMCHEM CO.,LTD supplies this compound, ensuring high standards of purity and quality for its diverse uses.

Chemically, N-n-Butyl benzene sulfonamide is characterized by a benzene ring attached to a sulfonamide group, which is further substituted with a butyl chain on the nitrogen atom. This structure imparts a balance of polarity and non-polarity, enabling it to interact effectively with a range of polymer matrices. Its physical form is typically a colorless to light yellow liquid, with a density of approximately 1.15 g/mL and a refractive index of around 1.525. These properties are crucial for its function as a plasticizer, influencing its solubility and compatibility with other materials.

The synthesis of N-n-Butyl benzene sulfonamide generally involves the reaction between butylamine and benzenesulfonyl chloride. This is a standard organic synthesis reaction where the amine nucleophilically attacks the sulfonyl chloride, forming the sulfonamide bond. The process requires careful control of reaction conditions, including temperature and reactant ratios, to ensure high yield and purity. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD employ optimized synthesis routes to produce material that meets stringent industrial specifications. The purity of the final product, often exceeding 99%, is critical for its performance as a plasticizer for polyamide and other sensitive applications.

The specific chemical characteristics of N-n-Butyl benzene sulfonamide, such as its relatively low volatility and good thermal stability, contribute to its effectiveness as a permanent plasticizer. Unlike some volatile plasticizers that can evaporate over time, N-n-Butyl benzene sulfonamide remains within the polymer matrix, providing long-lasting flexibility and performance benefits. This characteristic is highly valued in applications where material durability and consistent properties are essential. NINGBO INNO PHARMCHEM CO.,LTD's commitment to quality ensures that customers receive a product with these desirable chemical traits for their manufacturing processes.
