202-98-2 Usage
Uses
Used in Environmental Studies:
4H-Cyclopenta(def)chrysene is used as a marker for [identifying the presence and levels of PAHs in the environment] due to its moderate degree of carcinogenic activity. This helps in understanding the impact of PAHs on human health and the environment.
Used in Chemical Research:
As a PAH, 4H-Cyclopenta(def)chrysene is used as a subject of study in [chemical research] to understand the properties, behavior, and potential applications of PAHs in various fields, including material science and pharmaceuticals.
Used in Industrial Monitoring:
4H-Cyclopenta(def)chrysene is used as an indicator in [industrial monitoring] for assessing the level of PAH contamination in various industries, such as coal and oil production, where these compounds are commonly found as byproducts.
Carcinogenicity
4H-Cyclopenta[def]chrysene
was carcinogenic in two initiation–promotion experiments in
mice.
Check Digit Verification of cas no
The CAS Registry Mumber 202-98-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 202-98:
(5*2)+(4*0)+(3*2)+(2*9)+(1*8)=42
42 % 10 = 2
So 202-98-2 is a valid CAS Registry Number.

A New General Synthesis of Polycyclic Aromatic Compounds Based on Enamine Chemistry
Harvey, Ronald G.,Pataki, John,Cortez, Cecilia,Raddo, Pasquale Di,Yang, ChengXi
, p. 1210 - 1217 (2007/10/02)
Alkylation of enamines and enamine salts by benzylic and (β-haloethyl)aryl halides, respectively, followed by acidic cyclodehydration and dehydrogenation provides an efficient synthetic approach to a wide range of polycyclic aromatic compounds of diverse structural types.Specific polycyclic hydrocarbons synthesized by this route include benzo- and benzofluorene, 7H-dibenzo-, 13H-dibenzo-, and 13H-dibenzofluorene, 15H-tribenzofluorene, dibenzochrysene, benzopentaphene, indenofluorene, fluorenofluorene, octahydrodibenzanthracene, dibenzanthracene, octahydrodibenzanthracene, dibenzanthracene, picene, benzopicene, 1H-benzaceanthrylene, and 4H-cyclopentachrysene.This method with appropriate modifications appears to be potentially broader in scope than established traditional methods of polycyclic hydrocarbon synthesis.
