 Phenanthrenequinone (CAS NO.84-11-7) itself was pesticides, and it can be used as fungicides, seed dressing agents, electronic camera can be used as light guide materials, photosensitive solder preservative agents and paper.Phenanthrenequinone which is used in organic synthesis, can be used to produce benzene around the anthrone. Phenanthrenequinone with antimicrobial activity, for seed dressing to prevent corn smut, cotton seedling diseases, but also as a pulp preservative. The sodium hydroxide can be treated much more effective system of plant growth regulators shaping elements.
