5315-79-7 Usage
Uses
1. Used in Environmental and Occupational Health Studies:
1-Hydroxypyrene is used as a biomarker for assessing exposure to polycyclic aromatic hydrocarbons (PAHs) in various populations, such as aircraft maintenance workers and cokery workers in oil shale processing plants. It helps in investigating the effects of genetic polymorphisms on urinary 1-hydroxypyrene levels, which can be useful in understanding the impact of PAH exposure on human health.
2. Used in Analytical Chemistry:
1-Hydroxypyrene is used as a tracer compound for the fast detection and quantification of PAHs in tissue extracts from organisms exposed to sediment-associated pyrene. This application is particularly relevant in environmental studies, where understanding the bioavailability and toxicity of PAHs is crucial for assessing the health of ecosystems and the organisms within them.
Check Digit Verification of cas no
The CAS Registry Mumber 5315-79-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,1 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5315-79:
(6*5)+(5*3)+(4*1)+(3*5)+(2*7)+(1*9)=87
87 % 10 = 7
So 5315-79-7 is a valid CAS Registry Number.

Photo-Fries rearrangement of 1-pyrenyl esters

Photo-Fries rearrangement reactions of 1-pyrenyl esters were investigated. Photoreaction of 1-pyrenyl benzoate in benzene generates 1-hydroxy-2-pyrenyl phenyl ketone along with 1-pyrenol. The exceptionally down field 1H NMR chemical shift of OH proton in the photoproduct indicates the existence of intramolecular hydrogen bonding. Photorearrangements of analogs that have electron-withdrawing or electron-releasing group on the phenyl ring, and related heteroaromatic carboxylates also take place to form the corresponding ketones. However, photoreactions of 1-pyrenyl aliphatic carboxylate esters do not occur. The results of spectroscopic and theoretical studies suggest the mechanistic pathway for this process is initiated by homolytic C–O bond cleavage in an aroyl group localized 1(π → π?) excited state of the 1-pyrenyl esters. The radical pair generated in this fashion then undergoes in-solvent-cage coupling to yield the 1-hydroxy-2-pyrenyl aryl ketone selectively.
