Dibenzo[a,o]perylene is a polycyclic aromatic hydrocarbon (PAH) consisting of five fused benzene rings, with a molecular formula of C22H12. It is a black, crystalline solid that is insoluble in water but soluble in organic solvents. Dibenzo[a,o]perylene is formed during the incomplete combustion of organic materials, such as coal, wood, and fossil fuels, and is released into the environment as a byproduct of industrial processes and vehicle emissions. It is considered a persistent organic pollutant due to its resistance to degradation and its potential to bioaccumulate in living organisms. Exposure to dibenzo[a,o]perylene can lead to various health issues, including respiratory problems, skin irritation, and potential carcinogenic effects. As a result, it is classified as a hazardous substance and is subject to regulations aimed at reducing its release into the environment.

190-36-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 190-36-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 190-36:
(5*1)+(4*9)+(3*0)+(2*3)+(1*6)=53
53 % 10 = 3
So 190-36-3 is a valid CAS Registry Number.

Endoperoxide formation of helianthrene with triplet molecular oxygen. A spin-forbidden reaction

Seip,Brauer

, p. 4486 - 4490 (1992)

Dibenzo[A,o]perylene (helianthrene = HEL), known to be a very reactive singlet molecular oxygen (1O2, 1Δg) acceptor, also reacts with molecular oxygen in its triplet ground state (3O2,3∑-g) to form helianthrene endoperoxide (HELPO). The thermal endoperoxide formation was studied in several solvents at room temperature. In nonpolar solvents such as toluene and carbon disulfide the temperature-dependent equilibrium, HEL + 3O2 ? HELPO, is established by the thermolysis of HELPO even at low temperatures. Kinetic parameters for the HELPO formation in toluene are ΔH? = 10.2 ± 1.0 kcal mol-1 and ΔS? = -39 ± 5 eu, indicating that 1O2 is not involved in the reaction pathway. This is the first example of aromatic endoperoxide formation by reaction with molecular oxygen in its ground state.
