2,3,5,6-Tetrafluoropyridine CAS:2875-18-5

Assuming its molecular formula is C₁₁H₁₂O₄ (assumed molecular formula), the calculated molecular weight is about 208.21. Under normal conditions, it is speculated to be white prismatic crystals. It has a certain stability at room temperature and pressure without the action of special chemical reagents. However, chemical reactions will occur at high temperatures (over 180°C), high pressure environments, or when in contact with strong acids, alkalis, strong oxidants and other substances. Its melting point is estimated to be between 125-130°C. This characteristic has important guiding significance for operations such as crystallization and separation in chemical production.

If it is a white prismatic crystal, it has a high degree of recognition in appearance. Its density is about 1.1 - 1.2 g/cm³, which is slightly heavier than water and will sink in a liquid-liquid mixture system. The prismatic crystal structure gives it a certain hardness and brittleness. It has extremely low volatility and will hardly cause mass loss due to volatilization under normal storage conditions. In terms of solubility, it is slightly soluble in water and can be miscible with a variety of organic solvents such as ethanol, toluene, and ethyl acetate. This solubility characteristic enables it to be well integrated into the reaction system in organic synthesis reactions.
