3-methyl-4-heptyl oxybutyraldehyde

3-methyl-4-heptyl oxybutyraldehyde is a fragrance compound characterized by aldehydic and citrus odor notes used primarily in perfumery.

General Material Description

3-methyl-4-heptyl oxybutyraldehyde is an organic aldehyde used predominantly as a fragrance agent. It is recognized for its aldehydic and citrus olfactory characteristics, which impart fresh, orange-like, tangy, juicy, and zesty sensory impressions. The compound is also known under synonyms including 3-methyl-4-heptyloxy-butyraldehyde and 3-methyl-4-heptyloxybutyraldehyde. Structurally, it features an aldehyde functional group linked to a heptyloxy substituent on a butyraldehyde backbone. This compound’s chemical profile is indexed in public databases such as PubChem. Sourcing is typically synthetic via organic synthesis routes designed to yield fragrance intermediates.

Occurrence, Applicability & Potential Uses

This compound appears mainly through synthetic preparation and does not occur naturally in significant quantities. It is employed in fragrance formulations to deliver aldehydic and citrus nuances, enhancing the freshness and complexity of scents. Its usage is subject to standards such as IFRA (Global) to ensure safe application in consumer products. Although it is not approved for flavor use, it finds application exclusively within perfumery, where it contributes to creating bright and zesty aromatic profiles in various personal and household care products.

Physico-Chemical Properties Summary

3-methyl-4-heptyl oxybutyraldehyde combines hydrophobic alkyl chains with the polar aldehyde group, influencing its solubility and volatility. Its aldehydic character underpins its distinct odor, while the heptyloxy moiety contributes to moderate lipophilicity, aiding integration into fragrance bases. Its volatility enables effective volatilization in air, creating prominent odor perception at low concentrations. Its chemical stability under formulation conditions aids reliability in perfumery compositions. Overall, these properties allow controlled scent release and blending compatibility in complex fragrance systems.
