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

How Benzaldehyde Dimethyl Acetal differs from similar materials

Phenylacetaldehyde Dimethyl Acetal
Both are dimethyl acetals of aromatic aldehydes; benzaldehyde's is sweet floral-almond, phenylacetaldehyde's green and hyacinth-like.

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.
