6-methyl-4-oxo-1,4-dihydropyridine-3-carboxylic acid

6 - methyl - 4 - oxo - 1,4 - dihydropyridine - 3 - carboxylic acid, its chemical structure is an organic compound containing a pyridine ring. Looking at its name, its structural characteristics can be gradually analyzed.
"6 - methyl" is shown to be substituted by methyl ($- CH_3 $) at position 6 of the pyridine ring. "4 - oxo" means that position 4 of the pyridine ring is carbonyl ($C = O $). " 1,4-dihydropyridine "indicates that the 1 and 4 positions of the pyridine ring are in the form of dihydro, that is, the carbon atoms of the two positions are hybridized with $sp ^ 3 $. Unlike the carbon atoms hybridized with $sp ^ 2 $in the usual pyridine ring, this dihydro structure endows the molecule with a different electron cloud distribution and reactivity.
And" 3-carboxylic acid "indicates that there is a carboxyl group ($-OH CO$) attached to the 3 position of the pyridine ring. Overall, the structure of this compound is a pyridine ring as the core, with methyl, carbonyl and carboxyl groups attached at specific positions. Its unique structure makes the compound have special properties and applications in organic synthesis, medicinal chemistry and other fields. For example, carboxyl groups can participate in esterification, salt formation and other reactions; carbonyl groups can perform nucleophilic addition and other reactions; the existence of methyl groups also affects the steric resistance and electronic effects of molecules, which in turn affects their physicochemical properties and biological activities.

6-Methyl-4-oxo-1,4-dihydropyridine-3-carboxylic acid, this is an organic compound with specific physical properties.
Looking at its properties, it is mostly white to light yellow crystalline powder under normal conditions. When viewed in sunlight, the luster is soft, delicate and uniform.
When it comes to the melting point, it is about 190-195 ° C. When the temperature gradually rises near the melting point, the substance begins to slow down from solid to liquid. This process is smooth and orderly, like ice melting under warm sun.
In terms of solubility, it is slightly soluble in water, but in organic solvents such as ethanol and acetone, it has slightly better solubility. In ethanol, under stirring, it can be seen that part of the solution is dissolved, and the solution is slightly cloudy, just like a mist.
Stability is also an important characteristic. In a dry environment at room temperature, it is quite stable and can maintain its own chemical structure for a long time. However, if exposed to strong light, high temperature or high humidity, the stability gradually loses, or the chemical structure changes, just like a delicate flower that cannot resist the wind and rain.
Its density is about 1.4 g/cm ³, and the texture is relatively compact, which is within a certain range compared with the density of common organic compounds.
In addition, its smell is weak, close to the smell, and you can feel a faint special smell, which is difficult to describe exactly, but it is different from the common fragrance.
