Throughout the industry, China's pharmaceutical intermediate production has six major characteristics: First, the production enterprises are mostly private enterprises, flexible in operation, and the scale of investment is small, basically between several million and one or two million yuan; The geographical distribution of production enterprises is relatively concentrated, mainly in the areas centered on Taizhou, Zhejiang and Jintan, Jiangsu. Third, with the increasing emphasis on environmental protection issues, the pressure on production enterprises to build environmentally friendly treatment facilities increases; fast. After a product is generally available for 3 to 5 years, its profit margin will drop drastically, which will force enterprises to continuously develop new products or continuously improve production processes in order to maintain high production profits. Fifth, due to the high profit of pharmaceutical intermediate production. In the chemical products, the production process of the two is basically the same, so more and more small chemical companies have joined the ranks of producing pharmaceutical intermediates, resulting in increasingly fierce competition in the industry; sixth, compared with raw materials, production The profit margin of intermediates is low, and the production process of APIs and pharmaceutical intermediates is similar. Therefore, some enterprises have not only produced intermediates, but also used their own advantages to start producing APIs.
