78832-54-9 Usage
Description
2-NAPHTHOL-1,3,4,5,6,7,8-D7 is a stable isotope-labeled compound derived from 2-naphthol, a type of polycyclic aromatic hydrocarbon (PAH). It is characterized by the presence of seven deuterium atoms, which makes it a useful tool in analytical chemistry for tracking and quantifying PAH metabolites.
Uses
Used in Analytical Chemistry:
2-NAPHTHOL-1,3,4,5,6,7,8-D7 is used as a reactant for the preparation of stable isotope-labeled internal standards. These standards are essential for accurate quantification of PAH metabolites in biological samples, such as urine from smokers and nonsmokers.
Used in Toxicology and Environmental Health:
In the field of toxicology and environmental health, 2-NAPHTHOL-1,3,4,5,6,7,8-D7 serves as a valuable tool for assessing human exposure to PAHs, which are known carcinogens and environmental pollutants. By using this deuterated compound as an internal standard, researchers can more accurately measure the levels of PAH metabolites in urine, providing insights into the extent of exposure and potential health risks associated with PAHs.
Check Digit Verification of cas no
The CAS Registry Mumber 78832-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,3 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78832-54:
(7*7)+(6*8)+(5*8)+(4*3)+(3*2)+(2*5)+(1*4)=169
169 % 10 = 9
So 78832-54-9 is a valid CAS Registry Number.

Uranyl-Sensitized Photochemical Oxidation of Naphthalene by Molecular Oxygen. Role of Electron Transfer
Mao, Yun,Bakac, Andreja
, p. 7929 - 7933 (1997)
Naphthalene quenches the excited state *UO2(2+) in two parallel pathways: oxidation to naphthalene radical cation, C10H8(.+) (Φ = 0.3), and exciplex formation.The overall rate constant in aqueous acetonitrile containing 0.1 M H3PO4 has a value kq = 2.20E9 M-1 s-1.In the presence of O2, a portion of c10H8(.+) is converted to 2-formylcinnamaldehyde and several other products, the rest reacting with UO2(1+) by back electron transfer.
