4-Cyanopyridine (CAS: 100-48-1) is a chemical compound defined by its specific physical and chemical properties, which dictate its utility in various industrial processes. As a white crystalline powder, its purity level, often exceeding 99.0%, is a critical indicator of its quality and suitability for sensitive applications. Manufacturers carefully control parameters like water content, sulfated ash, and heavy metal limits to ensure that the 4-cyanopyridine produced meets international standards. Understanding these properties is fundamental for anyone involved in its procurement or application.

The synthesis of 4-cyanopyridine is a sophisticated process typically involving the reaction of 4-methylpyridine with ammonia and air in the presence of a catalyst at elevated temperatures. This method, refined by experienced manufacturers, yields a high conversion rate and an excellent product yield. The subsequent purification steps, including condensation and distillation, are crucial for achieving the desired purity. The meticulous attention to detail in its synthesis underscores why quality matters when sourcing this compound. For businesses looking for a reliable 4-cyanopyridine manufacturer, attention to these synthesis details and adherence to strict quality control measures are key differentiators.

Beyond its primary use as an intermediate, the exploration of 4-cyanopyridine's properties contributes to broader advancements in chemical science. Its melting point (76-79°C) and boiling point (196°C) are important parameters for handling and process design. When considering where to buy 4-cyanopyridine, opting for suppliers who provide detailed technical specifications and robust quality assurance, such as many leading manufacturers in China, ensures that your projects benefit from a consistent and high-performance intermediate.
