4b,4c,8b,8d-tetrahydrodibenzo[a,f]cyclopropa[cd]pentalene is a complex organic compound belonging to the class of polycyclic aromatic hydrocarbons. It features a unique structure with a cyclopropane ring fused to a dibenzopentalene framework, which consists of two benzene rings connected by a pentalenyl bridge. 4b,4c,8b,8d-tetrahydrodibenzo[a,f]cyclopropa[cd]pentalene is characterized by its four hydrogen atoms attached at positions 4b, 4c, 8b, and 8d, which contribute to its tetrahydro descriptor. The molecule's specific arrangement of carbon and hydrogen atoms gives it distinct chemical properties and potential applications in various fields, such as materials science and pharmaceuticals. However, due to its complex structure, it is not commonly found in nature and is typically synthesized in laboratory settings for research purposes.

2199-28-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2199-28-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2199-28:
(6*2)+(5*1)+(4*9)+(3*9)+(2*2)+(1*8)=92
92 % 10 = 2
So 2199-28-2 is a valid CAS Registry Number.

Flow-Vacuum Pyrolysis of Polycyclic Compounds, 6. Pyrolysis of Dibenzo 8 Hydrocarbons

Banciu, Mircea D.,Stanescu, Michaela D.,Petride, Aurica,Parvulescu, Luminitza,Pop, Mircea

, p. 2513 - 2518 (2007/10/02)

The flow-vacuum pyrolysis of dibenzo 8 hydrocarbons 2, 3, 4, and 5 are studied at 1 Torr and in the temperature range between 400 and 650 deg C.The following new transformations have been observed: 24, 2-->5, 3-->5, 34, 3-->2, 5-->11, the last three presenting analogies in the 8 and/or benzo 8 series.A reaction mechanism is suggested. - Key Words: Dibenzo 8 hydrocarbons / Flow-vacuum pyrolysis
