General Description
6-Fluoro-2-methyl-2H-indazole is a chemical compound categorized under the indazole class. It is characterized by the presence of a fluorine atom and a methyl group on the indazole base structure, specifically at positions 6 and 2 respectively. The 2H- in its name refers to the hydrogen at the 2nd position of the indazole structure. One of its significant properties is its potential as an intermediate in synthesis, useful in research and pharmaceutical applications. Details about its physical properties or toxicity are not commonly available and may require further study.
Check Digit Verification of cas no
The CAS Registry Mumber 348-39-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 348-39:
(5*3)+(4*4)+(3*8)+(2*3)+(1*9)=70
70 % 10 = 0
So 348-39-0 is a valid CAS Registry Number.

Direct N-Alkylation and Kemp Elimination Reactions of 1-Sulfonyl-1H-Indazoles
Tang, Meng,Chu, Bingjie,Chang, Xiaowei
, p. 2109 - 2116 (2018/07/31)
The reactions of 1-sulfonyl-1H-indazoles under basic conditions are discussed, and the direct N-alkylation and Kemp elimination reactions of these compounds are reported. A series of 2-(p-tosylamino)benzonitriles and N-alkyl indazoles were prepared in good yields. Moreover, the 2-(p-tosylamino)benzonitriles could be transformed into a diverse range of important derivatives in a one-pot reaction. This method was successfully applied to the total syntheses of quindolinone and cryptolepinone; quindolinone was prepared in a one-pot reaction from 1-sulfonyl-1H-indazole.
