Isobutyl cyanoacetate

Isobutyl cyanoacetate (CAS 13361-31-4) is an ester of cyanoacetic acid used as a reactive intermediate and monomer building block in specialty chemical manufacturing.

Where is Isobutyl cyanoacetate used?

• Pharmaceutical intermediates: precursor for heterocyclic compounds and active pharmaceutical ingredient scaffolds
• Agrochemicals: crop protection compounds incorporating the cyanoacetate moiety into herbicide or pesticide structures
• Polymer chemistry: monomer or co-monomer in cyanoacrylate-type systems and specialty adhesive formulations
• It also supports Knoevenagel condensation reactions at scale for industrial use.

Good to know: Its active methylene group and nitrile function make it a practical starting material. Technical grade is the primary commercially available specification, with purity levels typically confirmed by GC analysis.

Commercial specifications

• Purity confirmed by GC analysis
• Drum quantities; larger bulk through contract or toll manufacturing
