Application
Phenanthrene Zone Refined (number of passes: 30) serves as a highly purified form of phenanthrene, a polycyclic aromatic hydrocarbon (PAH) composed of three fused benzene rings. This compound, derived from coal tar, plays a crucial role in various industrial and research applications due to its unique chemical properties. Utilized extensively in the production of dyes, pharmaceuticals, and explosives, phenanthrene also holds significant value in biochemical research. It acts as a precursor in synthesizing important compounds like bile acids, cholesterol, and other steroids through its derivative, cyclopentanophenanthrene. This white crystalline substance, known for its weak aromatic odor and presence in cigarette smoke, exhibits valuable characteristics such as photosensitizing skin to light and possessing a blue fluorescence. The refined version ensures enhanced purity due to its multiple passes, making it particularly suitable for specialized applications that require high precision and quality.
