6-Chloro-H-pyrazolo [1,5-a] pyridine-2-carboxylic acid, this is an organic compound. Its physical properties are quite critical and related to many fields of application.
Looking at its appearance, under room temperature and pressure, it often shows a white to light yellow crystalline powder state, which is conducive to preliminary identification. Its texture is fine, dry to the touch, and there is no special sticky feeling.
Melting point is also an important physical property. It has been determined by many experiments to be around [X] ° C. The melting point is stable and can be melted at a specific temperature. This property is of great significance in the purification and identification of compounds, and helps researchers accurately distinguish the purity and characteristics of substances.
In terms of solubility, it has certain solubility in common organic solvents, such as dichloromethane, N, N-dimethylformamide (DMF), etc. In dichloromethane, a uniform dispersion system can be obtained by moderate stirring, but the solubility in water is not good. This solubility difference is closely related to the molecular structure, and there are hydrophobic groups in the molecule, which makes it difficult to dissolve in water with strong polarity, but more easily soluble in organic solvents with moderate polarity. This characteristic has a significant impact in the separation and purification step of organic synthesis.
Furthermore, its density is about [X] g/cm ³. Although the value seems ordinary, it actually plays a significant role in chemical production, storage and transportation. Density determines the quality of a substance in a specific volume, which is related to packaging, container selection and transportation safety planning.
In addition, the compound is stable under normal conditions, and its structure may change under extreme conditions such as high temperature, strong acid and alkali. Knowing this stability, during experiments and production operations, the appropriate environment and conditions can be selected to ensure that the properties of the compound remain unchanged and the reaction proceeds as expected.
