3355-43-9 Usage
Chemical structure
1-ethylphenanthrene is a polycyclic aromatic hydrocarbon (PAH) with a phenanthrene molecule and an ethyl group attached to it.
Industrial occurrence
It is commonly found as a byproduct of industrial processes, particularly those involving the burning of fossil fuels or the production of coal tar.
Environmental pollutant
1-ethylphenanthrene is considered an environmental pollutant due to its presence in industrial byproducts.
Health hazard
It is potentially hazardous to human health and is classified as a Group 2B carcinogen by the International Agency for Research on Cancer (IARC).
Carcinogenic potential
1-ethylphenanthrene is possibly carcinogenic to humans, meaning it may cause cancer.
Health effects
Exposure to 1-ethylphenanthrene has been linked to respiratory issues and may pose a risk of cancer development.
Environmental concern
It is important to minimize the release of 1-ethylphenanthrene into the environment and limit human exposure to this compound to reduce potential health risks.
Check Digit Verification of cas no
The CAS Registry Mumber 3355-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,5 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3355-43:
(6*3)+(5*3)+(4*5)+(3*5)+(2*4)+(1*3)=79
79 % 10 = 9
So 3355-43-9 is a valid CAS Registry Number.

Herein we report a novel palladium-catalyzed reaction that results in phenanthrene derivatives using aryl iodides, ortho-bromoben-zoyl chlorides and norbornadiene in one pot. This dramatic transformation undergoes ortho-C–H activation, decarbonylation and subsequent a retro-Diels–Alder process. Pleasantly, this protocol has a wider substrate range, shorter reaction times and higher yields of products than previously reported methods.
