Is the person upstairs advertising? Do all the companies listed produce pyridine? There are only three or four pyridine manufacturers in the world, and the above companies should all be their sales branches.

At present, pyridine is mainly produced by Nanjing Red Sun and Nantong Ruili Chemical. Nanjing Red Sun is mainly used for its own use and produces methylpyridine and pyridine chloride. It is basically not sold to the outside world.
