Safety Profile
USE WITH AWARENESSWhat Does Pentanedioic acid, 1-(4-formyl-2-methoxyphenyl) 5-[(1R,2S,5R)-5-methyl-2-(1-methylethyl)cyclohexyl] ester Smell Like?
This ester presents an intriguing duality – opening with crisp floral aldehydic tones reminiscent of crushed violet petals dipped in citrus, then unfolding into a sophisticated woody-ambergris heart with creamy undertones. The dry-down reveals a subtle musky warmth with vanillic facets, creating exceptional longevity. When diluted, it behaves like a molecular accord itself, offering both diffusion and tenacity.
Chemistry, Properties & Perfumer Guide
The Chemistry
This ester belongs to the class of substituted phenyl pentanedioates, combining a vanillin-derived aromatic moiety with a menthol-derived terpenoid structure. The synthesis typically involves esterification of the diacid with the respective alcohol and aldehyde precursors under controlled conditions. The stereochemistry at the cyclohexyl ring (1R,2S,5R configuration) contributes significantly to its odor profile, with the isopropyl group creating steric hindrance that modulates volatility.
