NBS and NCS, as important halogenation reagents, are used entirely as supplementary raw materials in the production of active pharmaceutical ingredients (APIs) or pharmaceutical intermediate. China's research on NBS and NCS production commenced from the late 1980s. The industries from succinic acid to N-bromosuccinimide(NBS) and N-chlorosuccinimide (NCS) are closely related. Most products are produced by order, and China servers as an exporter of NBS and NCS. However, there’s great difference in the sales price of them due to different product quality. What is the current situation of China's NBS& NCS production? How is China's NBS& NCS priced? What's China’s export situation of NBS& NCS? What's the future of China's NBS& NCS production? The report surveys Chinese NBS &NCS to answer the above questions from the aspects of technology, production, import & export, consumption and price. And forecast about the future market of China’s NBS & NCS is made in a scientific method.
