2-pyridineacetic acid, 5-methyl-

5-Methyl-2-pyridyl acetic acid is a kind of organic compound. Looking at its structure, the pyridine ring is connected to the acetic acid group, and the 5 position of the pyridine ring has methyl substitution.
In terms of its physical properties, under normal conditions, it may be a solid, but it also depends on specific conditions. Its melting point, boiling point and other characteristics are limited by the intermolecular forces. The magnitude of the intermolecular forces is also related to the characteristics of its structure. This compound has a certain polarity because it contains polar pyridine rings and carboxyl groups. It may have good solubility in polar solvents, such as water and alcohols, but it may have poor solubility in non-polar solvents, such as alkanes.
As for chemical properties, the presence of carboxyl groups gives it acidity. It can neutralize with bases to generate corresponding salts and water. In the field of organic synthesis, carboxyl groups can participate in many reactions, such as esterification with alcohols to form ester compounds. The nitrogen atom of the pyridine ring is rich in lone pair electrons and has a certain alkalinity, which can react with acids to form salts. At the same time, the pyridine ring can also participate in the electrophilic substitution reaction. The presence of methyl groups will affect the activity and selectivity of the reaction. Because methyl groups are the power supply groups, or the electron cloud density of the pyridine ring increases, the electrophilic substitution reaction is more likely to occur, and the substitution position may be influenced by the positioning effect of methyl groups and pyridine rings.
