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

6-Oxo-1,6-dihydropyridine-3-carboxylic acid has a unique chemical structure. Looking at this name, "6-oxo" has a monocarbonyl group ($C = O $) at the 6th position of the pyridine ring, which has a great influence on the reactivity and physical properties of the compound. "1,6-dihydropyridine" shows that the 1st and 6th positions of the pyridine ring are dihydro states, that is, the double bond structure of the original pyridine ring is hydrogenated at this position, resulting in changes in the electron cloud distribution and stability of the pyridine ring. And "-3 -carboxylic acid" explicitly states that there is a carboxylic group ($-COOH $) at the 3rd position of the pyridine ring. The carboxylic group is acidic and can participate in many chemical reactions, such as salt formation, esterification, etc.
Its overall structure is based on the pyridine ring as the basic skeleton, and the 6-position carbonyl group, the 1-position and 6-position hydrogenation, and the 3-position carboxylic group together build the chemical properties of this compound. Carbonyl groups can participate in nucleophilic addition reactions, and the unsaturation of the dihydropyridine part makes it capable of hydrogenation, oxidation, etc. The acid-base properties of carboxyl groups and the reaction activities of ester formation and amide formation give this compound broad application prospects in organic synthesis, medicinal chemistry and other fields. The various parts in its structure interact with each other and jointly determine the unique physical and chemical properties of the compound.

6-Oxo-1,6-dihydropyridine-3-carboxylic acid, that is, 6-oxo-1,6-dihydropyridine-3-carboxylic acid, is a kind of organic compound. Its common physical properties are as follows:
Looking at its appearance, under room temperature and pressure, it is mostly white to light yellow crystalline powder, which is easy to observe and distinguish. Its color is pure, and the crystalline morphology is regular. Under light, it may be visible with a fine luster, just like a gleaming dust.
When it comes to solubility, this compound exhibits unique properties in organic solvents. In common organic solvents, such as methanol and ethanol, it has certain solubility. Both methanol and ethanol are polar organic solvents, and there are specific interactions with 6-oxo-1,6-dihydropyridine-3-carboxylic acid molecules, such as hydrogen bonds, van der Waals forces, etc., so they can dissolve them. However, in water, the solubility is relatively limited. Although water is also a polar solvent, the strength and mode of interaction with the compound molecules are different from those of organic solvents, so that the degree of solubility in water is not high.

Determination of the melting point is an important means to identify organic compounds. Such a high melting point indicates that the compound has a strong intermolecular force and a relatively stable structure. A higher temperature is required to destroy the intermolecular force and transform it from a solid state to a liquid state.
In addition, its stability is also an important physical property. Under normal conditions, the chemical properties are relatively stable. When encountering extreme conditions such as strong acids, strong bases or high temperatures, a chemical reaction may occur, causing its structure to change. This stability is derived from the characteristics of chemical bonds within molecules. The chemical bonds between atoms interact to maintain the stability of the molecular structure. However, under extreme conditions, the chemical bonds may be destroyed, triggering chemical reactions.
