An unfamiliar synthetic carbonate ester; by analogy with similar small alkyl/alkynyl carbonate esters it likely reads as a light, fresh, slightly green-fruity aromatic material with a mildly ethereal, solvent-adjacent facet. Not enough reliable data to describe drydown character with confidence.AI · claude-opus-4-7

Colorless oily liquid.
Insoluble in water, almost insoluble in propylene glycol, soluble in alcohol and oils.
Powerful, penetrating green foliage odor, between violet leaf and cucumber, but rather pungent-gassy in its approach, not as pleasant as the higher esters.
Suggested for use in perfumes as a modifier for methyl heptin carbonate and other esters of acetylenic acids.
Produced from iso-valeraldehyde plus 3-methyl-n-but-l-yne.
