Related News: The downstream industry of the pharmaceutical intermediate industry is mainly the production of APIs, and the relationship between APIs and preparations is in the upstream and downstream industry chain. The consumer demand for downstream preparations will directly affect the demand for APIs.4-isothiocyanatobenzonitrile In the context of the new medicine policy, with the development of China’s R & D strength, the number of innovative drugs approved has been blown out, which further strengthened the demand and speed of industrialization of raw materials in China.2031-62-1 The term active pharmaceutical ingredient may refer to an active chemical within an FDA-regulated drug, or API might mean the entire drug with its active and inactive ingredients.318515-70-7 In 2004, the National Development and Reform Commission, the former Ministry of Health, and the Ministry of Finance jointly formulated and promulgated the Administrative Measures for the Configuration and Use of Large Medical Equipment. This method uses X-ray electronic computer tomography (CT) devices and medical magnetic resonance imaging equipment, digital subtraction angiography X-ray machines of 800 mA or more as the management products of large-scale medical equipment, Purchase and use need to be reported to the provincial health administrative department for approval before approval. However, in recent years, with the comprehensive coverage of medical insurance, such basic medical facilities are being widely popularized, and the relevant implementation rules have directly linked the number of equipment to the number of doctors. Therefore, as the demand for imaging equipment continues to increase, it will have a greater boosting effect on the upstream contrast agent and its raw material market.In 2004, the National Development and Reform Commission, the former Ministry of Health, and the Ministry of Finance jointly formulated and promulgated the Administrative Measures for the Configuration and Use of Large Medical Equipment.
