Benz[a]anthracen-8-ol is a polycyclic aromatic hydrocarbon (PAH) with the chemical formula C18H12O. It is a derivative of benz[a]anthracene, which is a known carcinogenic compound. Benz[a]anthracen-8-ol is formed by the addition of a hydroxyl group (-OH) to the 8th carbon atom of the benz[a]anthracene molecule. This chemical is not commonly used in industrial applications, but it can be found as a byproduct in certain combustion processes, such as the burning of coal, oil, and tobacco. Due to its structural similarity to benz[a]anthracene, it is also considered to have potential carcinogenic properties, and exposure to it should be minimized.

34501-23-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34501-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,5,0 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 34501-23:
(7*3)+(6*4)+(5*5)+(4*0)+(3*1)+(2*2)+(1*3)=80
80 % 10 = 0
So 34501-23-0 is a valid CAS Registry Number.

Tetrabutylammonium Hydroxide: A Reagent for the Base-Catalyzed Dehydration of Vicinal Dihydro Diols of Aromatic Hydrocarbons. Implications to Ion-Pair Chromatography

McCourt, David W.,Roller, Peter P.,Gelboin Harry V.

, p. 4157 - 4161 (1981)

Vicinal dihydro diols of benzopyrene and benzanthracene are dehydrated to their phenolic derivatives by the methanol eluate of reverse-phase (octadecylsilane) columns previously treated with tetrabutylammonium phosphate.Phenols are also produced by treating the dihydro diols with methanolic tetrabutylammonium hydroxide on removal solvent.In most cases the regioselectivity is markedly different from the acid-catalyzed dehydration.The in situ generated tetrabutylammonium phenoxides are converted to the butyl ethers at high temperatures (150 deg C) but not under th e conditions of dehydration (60 deg C).Tetraethylammonium and tetramethylammonium hydroxides also dehydrate dihydro diols, whereas potassium and sodium hydroxides do not.Dehydration does occur by treatment of dihydro diols with potassium hydroxide in the presence of 1,4,7,10,13,16-hexaoxacyclooctadecane (18-crown-6) and with sodium methoxide in the presence of tetrabutylammonium chloride.A mechanism is suggested.
