1576-68-7 Usage
General Description
3-Ethylphenanthrene is a polycyclic aromatic hydrocarbon (PAH) compound with the molecular formula C20H16. It is composed of three benzene rings fused together, with an ethyl group attached to one of the rings. This chemical is a highly stable and nonpolar organic compound that is commonly found in fossil fuels and coal tar. It is known to be a byproduct of incomplete combustion processes and is classified as a potential environmental pollutant. 3-Ethylphenanthrene is also considered to be a potential carcinogen and may pose health risks to humans and the environment. Due to its toxic nature, it is important to handle and dispose of 3-Ethylphenanthrene with caution and adhere to proper safety protocols.
Check Digit Verification of cas no
The CAS Registry Mumber 1576-68-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1576-68:
(6*1)+(5*5)+(4*7)+(3*6)+(2*6)+(1*8)=97
97 % 10 = 7
So 1576-68-7 is a valid CAS Registry Number.

On the Acetylation of Phenanthrene and 9-Chlorphenanthrene
Fernandez, Franco,Gomez, Generosa,Lopez, Carmen,Santos, Ana
, p. 15 - 21 (2007/10/02)
Friedel-Crafts acetylation of phenanthrene (1a) in sym-tetrachlorethane yields mixtures of 2-,3- and 9-acetylphenanthrenes (2a,3a,4).The distribution of isomers is found to depend strongly upon the method of mixing the reagents.Acetylation of 9-chlorophenanthrene (1b), perfomed by a variety of methods and solvents, led mainly to 3-acetyl-9-chlorophenanthrene (3b) (>/=85percent).Previously unreported 2-acetyl-9-chlorophenanthrene (2b) was found to form up to a maximum 11percent in nitrobenzene.
