109881-52-9 Usage
Uses
Used in Environmental Monitoring and Regulation:
2,3,7,8-Tetramethoxydibenzofuran is used as a target pollutant for monitoring and regulation by environmental agencies. Its presence in the environment is closely monitored to minimize its impact on human and environmental health due to its toxic nature and potential to bioaccumulate in food chains.
Used in Industrial Process Improvement:
TETRO is used as a byproduct indicator in industrial processes, such as waste incineration and chemical manufacturing. Its detection in these processes helps in the development of cleaner and more efficient methods to reduce the emission of harmful pollutants, including TETRO.
Used in Research and Toxicological Studies:
2,3,7,8-Tetramethoxydibenzofuran is used as a subject of research in toxicological studies to understand its adverse effects on reproductive and developmental systems in animals. This research aids in the development of strategies to mitigate the risks associated with TETRO exposure and to improve the safety of industrial processes that produce this pollutant.
Check Digit Verification of cas no
The CAS Registry Mumber 109881-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109881-52:
(8*1)+(7*0)+(6*9)+(5*8)+(4*8)+(3*1)+(2*5)+(1*2)=149
149 % 10 = 9
So 109881-52-9 is a valid CAS Registry Number.

Versatile oxidative approach to carbazoles and related compounds using MoCl5
Trosien, Simon,B?ttger, Philipp,Waldvogel, Siegfried R.
, p. 402 - 405 (2014/04/03)
The unique oxidizing power of molybdenum pentachloride provides an easy to perform, versatile, and high yielding method to construct carbazoles and the corresponding dibenzo analogues of thiophene, furan, and selenophene. The coupling reaction tolerates a variety of functional groups. The synthesis is highly modular. By this approach a precursor for the naturally occurring carbazole koenigicine was prepared.
Quinones and Quinone Methides. VII. Reactions of 1,4-Naphthoquinone and 1,4-Benzoquinones with 4-Hydroxy-2H-1-benzopyran-2-one and 5,5-Dimethylcyclohexane-1,3-dione in Acid Solutions
Jurd, Leonard
, p. 1603 - 1610 (2007/10/02)
4-Hydroxy-2H-1-benzopyran-2-one (4) reacts with 1,4-naphthoquinone, 2-methoxy-1,4-benzoquinone and 1,4-benzoquinone in aqueous acetic acid solutions to yield the quinone (6) and the quinols (11) and (2), respectively.With 5,5-dimethylcyclohexane-1,3-dione, 1,4-naphthoquinone forms a bisfurano compound (9) while 1,4-benzoquinone yields the bisfurano compound (18) and the monophenolic furano derivative (17).The blue product formed by acid catalysed dimerization of 2-methoxy-1,4-benzoquinone forms a diacetate, the n.m.r. spectra of which is in accord with structure (15b).
