42397-65-9 Usage
Description
1,8-Dinitropyrene is a nitro-substituted polycyclic aromatic hydrocarbon that exists at room temperature as a yellow fluffy or light-brown crystalline solid. It is a potent mutagenic component of diesel exhaust and air pollutants, with a molecular weight of 292.3 and a melting point of over 300°C.
Uses
1. Research Applications:
1,8-Dinitropyrene is used as a research compound for studying its properties and potential applications. It is available at a purity of at least 99% and in 14Cor 3H-labeled form at a radiochemical purity of at least 98%.
2. Environmental Studies:
1,8-Dinitropyrene is used as a marker for environmental contamination, particularly in sediments, due to its mutagenic properties and potential carcinogenic effects on humans.
3. Photodecomposition Studies:
1,8-Dinitropyrene is used in the investigation of photodecomposition processes when exposed to light (≥ 310nm) in various mediums, such as DMSO or coated onto silica.
4. Diesel Exhaust and Air Pollutant Research:
1,8-Dinitropyrene is used as a study subject in research related to diesel exhaust and air pollution, as it is a potent mutagenic component of these environmental contaminants.
Note: Although 1,8-Dinitropyrene has been reported to be a photosensitizer, there is no evidence that it has ever been used commercially for this or any other purpose.
Carcinogenicity
1,8-Dinitropyrene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
Check Digit Verification of cas no
The CAS Registry Mumber 42397-65-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,3,9 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42397-65:
(7*4)+(6*2)+(5*3)+(4*9)+(3*7)+(2*6)+(1*5)=129
129 % 10 = 9
So 42397-65-9 is a valid CAS Registry Number.
