Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes, as a scintillator to detect high energy particles, as production of pharmaceutical drugs.

Anthracene can cause cancer according to California Labor Code and the World Health Organization's International Agency for Research on Cancer (IARC). Anthracene is a white to yellow solid with a weak aromatic odor. Sinks in water. (USCG, 1999) U.S. Coast Guard. 1999. Chemical Hazard Response Information System (CHRIS) - Hazardous Chemical Data.

Dithranol (INN) or anthralin (USAN and former BAN) is a hydroxy anthrone, anthracene derivative, and is used in medications applied to the skin of people with psoriasis.

Anthralin (1,8‐dihydroxy‐9anthrone, dithranol) is an older anti-psoriatic agent that was first synthesized as a derivative of chrysarobin, obtained from the araroba tree in Brazil over 100 years ago. Adverse effects of anthralin include irritation and discoloration of the skin.

2020年6月8日 · Anthracene is one of the smaller polynuclear aromatic hydrocarbons. (The only smaller one is naphthalene.) It was isolated from coal tar in 1832 by pioneering French chemists Jean-Baptiste Dumas and Auguste Laurent. Anthracene can be synthesized by the Elbs reaction, in which o -tolyl phenyl ketone is dehydrated at 400–450 ºC.

Anthracene was first discovered in coal tar by Jean B.A. Dumas and Auguste Laurent in 1832. The importance of anthracene for industrial aromatic chemistry began with the synthesis of the dyestuff alizarin by Carl Graebe and Carl Th. Liebermann, as well as by William H.Perkin in 1868, replacing the natural dye produced from madder.

Anthracene is a solid polycyclic aromatic hydrocarbon consisting of three fused benzene rings. You might find these chapters and articles relevant to this topic. Anthracene is photosensitizing. It can cause acute dermatitis with symptoms of burning, itching, and edema, which are more pronounced in the exposed bare skin regions.

Although not often prescribed nowadays, dithranol (also called anthralin) is one of the most effective preparations available for treating psoriasis. In New Zealand, dithranol is available at pharmacies as a 1% cream called Micanol Cream. Consult your dermatologist to see if it's suitable for your skin problem.
