Monitoring levels of this metabolite can help assess the extent of PAH contamination and potential health risks.
Used in Pharmaceutical Research:
In the pharmaceutical industry, Benz(a)anthracen-9-ol is used as a research compound for [application type] in the development of drugs targeting PAH-related diseases for [application reason] its structural similarity to PAH toxins allows researchers to study their mechanisms of action and develop targeted therapies.
Used in Analytical Chemistry:
Benz(a)anthracen-9-ol is used as a reference material in analytical chemistry for [application type] in the calibration and validation of analytical instruments and methods for [application reason] its distinct chemical properties make it a suitable candidate for ensuring accurate and reliable measurements of PAH toxins and their metabolites in various samples.
Check Digit Verification of cas no
The CAS Registry Mumber 34570-62-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,5,7 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34570-62:
(7*3)+(6*4)+(5*5)+(4*7)+(3*0)+(2*6)+(1*2)=112
112 % 10 = 2
So 34570-62-2 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 (2007/10/02)
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.
