Use

Phenanthrenequinone is a pesticide used as germicide seed dressing, being able to prevent wheat scab, hard smut and sweet potato black spot. Phenanthrene, through the oxidation, can give phenanthrenequinone, to be used to replace the organic mercurial pesticides ceresin and gallotox. It can be used for the manufacturing of phenanthrenequinone, synthetic resin, pesticides and preservatives and so on. Industrial Phenanthrene is derived from distillation of anthracene oil derived from coal tar distillate. Many kinds of natural products (such as sterols) contain this ring system. Phenanthrene is mainly used in the manufacture of dyes, drugs, high efficiency and low toxicity of pesticides, and can be used as scintillants, smokeless powder stabilizer. Many of the phenanthrene derivatives have carcinogenic physiological effects.
