42397-65-9 Usage
Chemical Properties
1,8-Dinitropyrene is a nitro-substituted polycyclic aromatic hydrocarbon that exists at room temperature as a yellow fluffy or light-brown crystalline solid (IARC 1989). It has a molecular weight of 292.3 and a melting point of over 300°C (HSDB 2009).
Uses
Different sources of media describe the Uses of 42397-65-9 differently. You can refer to the following data:
1. 1,8-Dinitropyrene has been reported to be a photosensitizer; however,there is no evidence that it has ever been used commercially for this or any other purpose (IARC 1989). 1,8-Dinitropyrene is available for research purposes at a purity of at least 99% and in 14C- or 3H-labeled form at a radiochemical purity of at least 98%.
2. 1,8-Dinitropyrene is one of the major mutagens found in contaminated sediments. Also a potential human carcinogen.
General Description
The photodecomposition of environmental contaminant, 1,8-dinitropyrene via exposure to light (≥ 310nm) either in DMSO, or following coating onto silica has been investigated. 1,8-Dinitropyrene is a potent mutagenic component of diesel exhaust and air pollutant.
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.
