What are the physical and chemical properties of 1-(2-Chloro-3-pyridinyl)ethanone (CAS: 55676-21-6)?

1-(2-Chloro-3-pyridinyl)ethanone is a crystalline solid with a molecular weight of approximately 182.69 g/mol. It has a solubility of about 0.32 g/100 mL in water. Chemically, it is mildly reactive, particularly in the presence of moisture and air. It is stable at room temperature and under normal atmospheric conditions, but care should be taken to store it in a dry and cool place to prevent hydrolysis.
