Our technical approach focuses on the synthesis of heterocyclic compounds in a region-selective manner. Our R&D team has successfully overcome the limitations of traditional synthesis methods by leveraging over 50 unique patents and over 20 years of process knowledge. Through our innovative application of the "heterogeneous catalysis - continuous flow reaction" coupling technology, the regional selectivity of the synthesis of important intermediates has increased by more than 30%. The product purity remains at 99.5% or higher, and the impurity control accuracy reaches the ppm level, fully meeting the strict specification requirements of high-end applications such as pharmaceuticals and electronic grade.
