Phenanthrene is an isomer of anthracene and has three benzene rings fused together but not arranged in a straight line. Chemical formula: C14H10. (organic chemistry) A tricyclic aromatic hydrocarbon obtained from coal tar; used in the manufacture of dyes, pharmaceuticals and explosives; it is isomeric with anthracene.

What is the structure of phenanthrene?

Phenanthrene/Formula

What is the uses of phenanthrene?

Like most PAHs, phenanthrene is used to make dyes, plastics and pesticides, explosives and drugs. It has also been used to make bile acids, cholesterol and steroids.

What are the properties of phenanthrene?

The phenanthrene is a colorless crystal with luster, and the phenanthrene precipitated from ethanol is a colorless monoclinic crystal. The phenanthrene is a leaf-like crystal with a relative density of 1.179 (25/4 ℃) and a refractive index of 1.6450, melting point of 101 °C and boiling point of 340 °C.

Why is phenanthrene aromatic?

Phenanthrene is more stable than anthracene due to the larger stability of the π-system of the former, which is more aromatic.

Is Buprenorphine a phenanthrene?

Buprenorphine Hydrochloride is the hydrochloride salt form of buprenorphine, a synthetic phenanthrene with narcotic analgesic activity. Buprenorphine hydrochloride is a partial agonist at the mu-opioid receptor and an antagonist at the kapa-opioid receptor in the central nervous system.

Why is phenanthrene more reactive than anthracene?

Phenanthrene is more stable than anthracene due to the larger stability of the π-system of the former, which is more aromatic. The larger stability of the former also correlates with its larger aromaticity, despite the difference in aromaticity between the isomers is now smaller.

What is phenanthrene made of?

The name ‘phenanthrene’ is a composite of phenyl and anthracene. In its pure form, it is found in cigarette smoke and is a known irritant, photosensitizing skin to light. [citation needed] It appears as a colorless, crystal-like solid but can also look yellow.

What is the meaning ofphephenanthrene?

phe·nan·threne. A compound isomeric with anthracene, derived from coal tar; a major component of steroids, as cyclopenta[α]phenanthrene. Used as a basis for the synthesis and nomenclature of various dyes and drugs.

What are the reagent reactions of phenanthrene?

Reactions of phenanthrene typically occur at the 9 and 10 positions, including: Organic oxidation to phenanthrenequinone with chromic acid Organic reduction to 9,10-dihydrophenanthrene with hydrogen gas and raney nickel Electrophilic halogenation to 9-bromophenanthrene with bromine

Is phenanthrene soluble or insoluble in water?

Chemistry Phenanthrene is nearly insoluble in water but is soluble in most low polarity organic solvents such as toluene, carbon tetrachloride, ether, chloroform, acetic acid and benzene. The Bardhan–Sengupta phenanthrene synthesis is a classic way to make phenanthrenes.
