[0002] Fluorinated intermediates are mainly used in the production of APIs in the pharmaceutical industry. Trends show that in the production of pharmaceutical compounds, the demand for aromatic fluorinated intermediates is becoming more and more common, and their proportion in drug varieties is increasing. Organic fluorinated compounds have strong stability, physiological activity, fat solubility and sulfur-water properties, and can adjust parameters such as electronics and lipophilicity. Therefore, many fluorinated drugs have relatively small dosage, low toxicity, high efficacy, and strong metabolic capacity in terms of performance, which has a significant impact on the pharmacodynamics and pharmacokinetic properties of drugs. Due to the superior performance of fluorinated drugs, the research and development of fluorinated drugs has promoted the expansion of the domestic and foreign markets for fluorinated intermediates.
