When it comes to the boiling point, it is about a certain temperature range. Due to the interaction of van der Waals force and hydrogen bonds between molecules, a specific energy is required to make the molecule break free from the liquid phase and turn into the gas phase. The molecular weight, the size of the intermolecular force and other factors determine its boiling point value.
As for the melting point, it is also in a specific temperature range. When the temperature drops to the melting point, the thermal motion of the molecule slows down, and the intermolecular force prompts it to be arranged in an orderly manner to form a crystal structure.
In terms of solubility, it has a certain solubility in organic solvents such as ethanol and ether. Due to the principle of "similar miscibility", the molecular structure of the compound has a certain similarity with the molecular structure of the organic solvent, and can be mixed with each other through the intermolecular force. However, the solubility in water is not good, because the polarity of molecules and water molecules is quite different, and the interaction force is weak, so it is difficult to dissolve.

1% 2C2-dioxy-4-methyl-3-furyl-5- (trichloromethyl) pyridine, this is an organic compound. As for whether its chemical properties are stable, let me tell you one by one.
Among this compound, the dioxy structure, methyl group, furyl group and trichloromethylpyridine part all affect its stability. The dioxy structure is relatively stable, because its chemical bond energy distribution is in a certain equilibrium state. As an alkyl group, methyl group has a certain electron-giving effect, which can affect the electron cloud density of connected groups. However, this effect on the stability does not pose a significant threat, because its spatial steric resistance and electronic effects are still within a certain controllable range.
The presence of furanyl groups, because it is an aromatic five-membered heterocyclic ring, although it has certain stability, the presence of heteroatomic oxygen makes the electron cloud distribution on the ring uneven. Under certain conditions, it may initiate a reaction and affect the overall stability.
And the trichloromethyl pyridine part, the chlorine atom has strong electron absorption, which will reduce the electron cloud density of the pyridine ring and change the reactivity on the pyridine ring. The steric resistance of trichloromethyl is also large, which may affect the interaction between molecules.
Overall, the chemical properties of 1% 2C2-dioxo-4-methyl-3-furanyl-5- (trichloromethyl) pyridine are relatively stable under normal conditions. In case of special conditions such as high temperature, strong acid-base, strong oxidizing agent or reducing agent, all parts of its structure are affected by the comprehensive effect of electronic effect and space effect, or chemical reaction may occur, and the stability will be changed accordingly. Therefore, when storing and using this compound, it is necessary to choose suitable conditions according to its characteristics to ensure its stability and safety.
