Sebacoyl Chloride (MF: C₁₀H₁₆Cl₂O₂ MW: 239.14) is a significant organic synthesis intermediate. It is a derivative of sebacic acid, produced by reacting its carboxyl group with chlorinating reagents such as thionyl chloride. Its molecular structure contains two acyl chloride groups (-COCl), conferring high reactivity and making it a key raw material for synthesising numerous organic compounds.
