Typical role: modifier (used in small amounts to change the character of a blend).

How Ethyl Heptanoate differs from similar materials

Ethyl Hexanoate
Ethyl hexanoate is pineapple and green apple; ethyl heptanoate, one carbon longer, is described as wine and brandy.

Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
