Isobutyl cyanoacetate

Isobutyl cyanoacetate (CAS 13361-31-4, EC 236-422-9) is a cyanoacetate ester also referred to as IBCY, isobutyl 2-cyanoacetate, or cyanoacetic isobutyl ester. It carries no assigned E-code and is classified under HS code 29269090 within the broader category of pharmaceutical intermediates.

In pharmaceutical synthesis, isobutyl cyanoacetate serves as a reactive building block in Knoevenagel condensations, where its active methylene group undergoes condensation with aldehydes to form intermediates for active pharmaceutical ingredients. In polymer chemistry, it functions as a polymerization initiator and monomer precursor, contributing to the formation of cyanoacrylate-based materials used in adhesive and coating formulations.

Isobutyl cyanoacetate is supplied as a technical-grade material and is subject to REACH registration requirements for EU-based procurement. Standard packaging formats follow conventional liquid chemical handling protocols. Buyers should confirm purity specifications and documentation requirements directly with the supplier prior to order placement.
