diphenylene-methan Introduction: diphenylene-methan, also fluorene or 9H-fluorene, is extracted from coal tar products, and its upstream products is washing oil or coal tar products, downstream products fluorenone, fluorene methanol, and other synthetic chemical products. It can be used widely in chemical research, pharmaceutical manufacturing, agriculture insecticide and organic synthesis. We, Xiaoyi Jinjing Chemical, are a factory supplier to R & D tar coal products for 11 years. And we are very glad to establish business relationship with more overseas factories in chemical industry, medicine manufacturing, biologic agriculture fields, to provide our diphenylene-methan products with good quality and best price.
