Isobutyl cinnamate, identified by CAS number 122-67-8, is a clear, colorless to pale yellow liquid ester derived from the esterification of cinnamic acid with isobutanol. It is recognized for its distinctive aromatic profile, which combines sweet, balsamic, and fruity notes reminiscent of cocoa, amber, and dried fruits. This chemical intermediate is valued for its stability and its ability to act as a fixative in various aromatic formulations, bridging the gap between volatile top notes and heavier base components.
In a laboratory or industrial setting, isobutyl cinnamate is handled as a stable organic compound, though standard precautions regarding its storage in cool, dry areas away from strong oxidizing agents are recommended. Its chemical structure, featuring a phenyl ring conjugated with an unsaturated ester group, makes it a versatile building block in organic synthesis and a crucial component for developing complex sensory profiles in consumer products. Its reliable performance and characteristic scent profile make it a staple in both research applications and large-scale manufacturing.
