61921-39-9 Usage
General Description
4-Bromobenzo[a]anthracene is a polycyclic aromatic hydrocarbon (PAH) and a known environmental pollutant with potential carcinogenic properties. It is commonly used in laboratory research as a chemical carcinogen to induce tumors in experimental animals, particularly in studies related to cancer research. The compound is highly lipophilic and can accumulate in the fatty tissues of organisms, posing a potential threat to human health and the environment. Exposure to 4-Bromobenzo[a]anthracene has been associated with adverse health effects, including DNA damage, oxidative stress, and the development of various types of cancer. It is crucial to handle and dispose of this chemical with caution to minimize its potential impact on human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 61921-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,2 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 61921-39:
(7*6)+(6*1)+(5*9)+(4*2)+(3*1)+(2*3)+(1*9)=119
119 % 10 = 9
So 61921-39-9 is a valid CAS Registry Number.

Policyclic Fluoranthene Hydrocarbons. 2. A New General Synthesis
Cho, Bongsup P.,Harvey, Ronald G.
, p. 5668 - 5678 (2007/10/02)
A novel and efficient synthetic approach to policyclic fluoranthene hydrocarbons is described.The method entails fusion of an indeno ring to an appropriate alternant hydrocarbon via reaction of its aryllithium derivative with cyclohexene oxide, followed by oxidation, cyclodehydration, and aromatization.Cyclization of the cyclohexanone and cyclohexanol derivatives of the policyclic aromatic ring systems studied proceeds with high regioselectivity, and the direction of ring closure is predictable by molecular orbital methods.This synthetic approach provides a convenient general route to polyaromatic fluoranthene compounds, including potentially carcinogenic members of this class.Hydrocarbons synthesized by this method include benzacephenanthrylene (1), indenopyrene (2), indenochrysene (3), benzindenochrysene (4), fluorenochrysene (5), dibenzaceanthrylene (6), dibenzaceanthrylene (7), benzaceanthrylene (8), benzindenochrysene (9), fluorenochrysene (10), and dibenzacephenanthrylene (11).
