Hexanoyl chloride is an acyl chloride used primarily in organic synthesis to introduce hexanoyl functional groups into compounds, such as in the preparation of esters, amides, and other derivatives. It is a reactive intermediate in pharmaceuticals, agrochemicals, and polymer chemistry. This clear to pale yellow liquid has a pungent odor and must be handled with care due to its corrosive and reactive nature. Key specifications include a CAS number of 142-61-0, molecular formula C6H11ClO, and a molecular weight of 134.60 g/mol. It should be stored at ambient conditions in a cool, dry place, away from moisture and incompatible materials. The product carries a **Danger** signal word, indicating severe hazards. Molekula supplies Hexanoyl chloride from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
