Ethyl 2-chloroacetoacetate is a versatile chlorinated ester widely used as an intermediate in organic synthesis, particularly for producing amino acids, heterocycles, and pharmaceuticals. It serves as a key building block in the production of active pharmaceutical ingredients (APIs) and agrochemicals due to its reactive chloro and ester functional groups. This chemical has a CAS number of 609-15-4, a molecular formula of CH3COCH(Cl)COOCH2CH3, and a molecular weight of 164.59 g/mol. It is typically stored at ambient temperatures but requires careful handling due to its hazardous nature, indicated by a "Danger" signal word. Molekula supplies Ethyl 2-chloroacetoacetate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
