2-Amino-3-nitro-4-methyl-5-fluoropyridine

2-Amino-3-nitro-4-methyl-5-fluoropyridine, this is an organic compound. Its chemical properties are unique and allow me to elaborate.
Looking at its structure, amino, nitro, methyl and fluorine atoms are all attached to the pyridine ring. Amino is basic, because its nitrogen atom has lone pair electrons, it can accept protons, and it is easy to combine with protons to form cations in acidic environments. This property makes it possible to participate in many acid-base reactions.
Nitro is a strong electron-absorbing group, which can reduce the electron cloud density of the pyridine ring and reduce the activity of electrophilic substitution on the ring. And the presence of nitro groups makes the compound oxidizing to a certain extent. When encountering reducing agents, nitro groups can be reduced to form amino groups or other reduced nitrogen-containing groups.
methyl is a donator group. Although the donator ability is relatively weak, it can also affect the distribution of electron clouds in the pyridine ring, which increases the density of electron clouds in the adjacent and para-position, and has a certain effect on the selectivity of the reaction check point.
Fluorine atoms have large electronegativity and have a strong electron-absorbing induction effect. They not only change the electron cloud density of the pyridine ring, but also have a significant impact on the physical and chemical properties of the molecule. For example, by enhancing the polarity of the molecule, it affects its solubility, melting point, boiling point and other physical properties. < Br >
