It is a pale yellow solid with a molecular formula of C14H14O4. 2,3,6,7-TETAMETHOXYNAPHTHALENE is primarily used as a fluorescent dye in various biological and pharmaceutical applications. It is also used as an intermediate in the synthesis of other chemicals. 2,3,6,7-Tetramethoxynaphthalene has been studied for its potential use in electronic devices and organic photovoltaic cells due to its light-emitting properties. However, it is important to handle this compound with care as it may be harmful if ingested and can cause irritation to the skin and eyes.
Check Digit Verification of cas no
The CAS Registry Mumber 33033-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,3 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33033-33:
(7*3)+(6*3)+(5*0)+(4*3)+(3*3)+(2*3)+(1*3)=69
69 % 10 = 9
So 33033-33-9 is a valid CAS Registry Number.

A simple route to derivatives of benzo[j]fluoranthene

3,6,8,11-Tetramethoxybenzo[j]fluoranthene can be made from 1,6-dimethoxynaphthalene in a one-pot ferric chloride oxidation/methanol reduction procedure. The reaction is tolerant of the presence of substituents in the 7-position of the naphthalene nucleus and provides a quick and easy route to these particular benzo[j]fluoranthenes. The reactions presumably proceed through initial formation of a bond between the 4-positions of two naphthalene molecules followed by closure of the five-membered ring. Indeed in one case some 4,4′-binaphthyl was isolated from the reaction mixture and it was generally found that better yields of the benzo[j]fluoranthrenes were obtained starting from the 4,4′-binaphthyl rather than by using the naphthalene as the starting material. In an analogous manner to the ring-closure of the 4,4′-binaphthyls, starting from a hexakisalkoxyphenylnaphthalene, a hexakisalkoxyfluoranthene could be obtained.
