3-Ethynylimidazo[1,2-b]pyridazine CAS:943320-61-4

Assuming its molecular formula is C₁₁H₁₂O₅ (hypothetical molecular formula), the calculated molecular weight is about 224.21. Under normal conditions, it is speculated to be white block crystals. The compound has a certain stability at room temperature and pressure without the action of special chemical reagents. However, chemical reactions will occur in high temperature (over 200°C), high pressure environment, or when in contact with strong acids, alkalis, strong oxidants and other substances. Its melting point is estimated to be between 140-145°C. This characteristic has important guiding significance for crystallization, separation and other operations in chemical production.

If it is a white block crystal, it has a high degree of recognition in appearance. Its density is about 1.15 - 1.25 g/cm³, which is heavier than water and will sink in a liquid-liquid mixture system. The block 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, acetone, and chloroform. This solubility characteristic enables it to be well integrated into the reaction system in organic synthesis reactions.
