6-Oxo-1,6-dihydropyridine-2-carboxylic acid has a unique chemical structure. In this compound, the pyridine ring is its core structure, and the nitrogen atom on the ring forms a specific covalent bond with the adjacent carbon atom to form a stable ring system. 6-oxo, that is, the sixth position of the pyridine ring is a carbonyl group (C = O), which gives the compound unique chemical activity and plays a key role in many chemical reactions. Because of its electrophilicity, it can react with nucleophiles.
Furthermore, 1,6-dihydropyridine indicates that the 1st and 6th positions of the pyridine ring are dihydrogen states, that is, the carbon atoms of this two positions are not completely connected to other atoms in the ring by double bonds, but have hydrogen atoms. This structural feature affects the electron cloud distribution and stability of the compound, making its reactivity different from that of conventional pyridine derivatives.
And 2-carboxylic acid refers to the connection of a carboxyl group (-COOH) at the 2nd position of the pyridine ring. The carboxylic group is acidic and can participate in acid-base reactions.

6-Oxo-1,6-dihydropyridine-2-carboxylic acid is one of the organic compounds. It has many important physical properties, which are described as follows:
Looking at its properties, it is mostly in a solid state under normal conditions. Due to the strong interaction forces between molecules, such as hydrogen bonds, van der Waals forces, etc., the molecules are arranged in an orderly manner, so they appear in a solid state.
As for the melting point, it has been experimentally determined to be about [X] ° C. The value of the melting point is closely related to the molecular structure. The compound has a conjugated system and polar groups in the molecule, which enhances the intermolecular force. To transform it from a solid state to a liquid state, more energy needs to be supplied to overcome the intermolecular force, which is why the melting point is in a specific range.
In terms of solubility, the degree of solubility in water is limited. This is because although there are carboxyl groups in the molecule that can form hydrogen bonds with water, the pyridine ring part is a hydrophobic structure, and as a whole, it limits its solubility in water. However, in polar organic solvents such as dimethyl sulfoxide (DMSO), N, N-dimethylformamide (DMF), the solubility is quite good. Due to the fact that these organic solvents can form similar interaction forces with the molecules of the compound, according to the principle of "similar miscibility", they can be well miscible with each other.
Its density is about [X] g/cm ³. The density depends on the mass of the molecule and the way of packing. The molecular structure of the compound is specific, and the mass and the tightness of molecular packing work together to cause the density to be in this value range.
The physical properties of this compound are of great significance for its application in chemical synthesis, drug development and other fields. Only by clarifying its physical properties can we reasonably choose the reaction solvent and control the reaction conditions in actual operation to achieve the expected experimental and application results.
