3397-78-2 Usage
General Description
4-Methoxycinnoline is a chemical compound that belongs to the class of cinnolines, which are heterocyclic aromatic compounds. It is characterized by a molecular structure containing a six-membered ring consisting of five carbon atoms and one nitrogen atom, with a methoxy group attached to the aromatic ring. 4-Methoxycinnoline has potential applications in the pharmaceutical and agrochemical industries due to its diverse biological activities, including anti-inflammatory and antimicrobial properties. It is also used as a building block in the synthesis of various organic compounds. However, further research and development are needed to fully understand and harness the potential of 4-Methoxycinnoline for practical applications.
Check Digit Verification of cas no
The CAS Registry Mumber 3397-78-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,9 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3397-78:
(6*3)+(5*3)+(4*9)+(3*7)+(2*7)+(1*8)=112
112 % 10 = 2
So 3397-78-2 is a valid CAS Registry Number.

On the tautomerism of cinnolin-4-ol, cinnoline-4-thiol, and cinnolin-4-amine

Detailed NMR spectroscopic investigations (1H, 13C, 15N) with cinnolin-4-ol (1) reveal this compound to exist exclusively in the cinnolin-4(1H)-one form in deuteriodimethyl sulfoxide solution. This finding is confirmed by comparison of the NMR spectroscopic data of 1 with those of the corresponding 'fixed' O-methyl and N-methyl derivatives, i.e. 4-methoxycinnoline (3) and 1-methylcinnolin-4(1H)-one (5). Similarly, cinnoline-4-thiol (4) is present in the thione form in deuteriodimethyl sulfoxide, whereas cinnolin-4-amine (7) exists in the amino form. In addition, in-depth analyses of the NMR spectra of some simple 4-substituted cinnolines are provided.
