Ethyl 7-Chloro-2-Oxoheptanoate (78834-75-0)

Ethyl 7-Chloro-2-Oxoheptanoate is a chlorinated keto ester widely used as an intermediate in pharmaceutical, agrochemical, and fine chemical synthesis. It appears as a colorless to pale yellow liquid and is soluble in most organic solvents while being practically insoluble in water. Its chemical formula is C9H15ClO3, and it has a molecular weight of 222.67 g/mol.

The presence of both ketone and ester functional groups, along with a reactive chlorine atom, makes it a versatile building block for the preparation of heterocyclic compounds, active pharmaceutical ingredients (APIs), and specialty chemicals. It is commonly employed in organic synthesis for nucleophilic substitution, condensation, and cyclization reactions. Due to its reactivity, the compound should be handled with appropriate safety precautions, avoiding direct contact with skin, eyes, and respiratory pathways. Proper storage in a cool, dry, and well-ventilated environment helps maintain its stability and quality during use and transportation.
