Nonan1one

Nonan-1-one, also known as 1-nonanone or heptyl methyl ketone, is a chemical compound with the molecular formula C9H18O. It is a ketone, characterized by a carbonyl group (C=O) bonded to two alkyl groups. In this case, the carbonyl group is attached to a seven-carbon chain (heptyl group) and a methyl group. It is a colorless liquid at room temperature and possesses a fruity, somewhat floral odor.

This compound occurs naturally in various plants and essential oils, contributing to their aroma profiles. For instance, it has been identified in ylang-ylang oil and some types of fruit. Due to its scent properties, nonan-1-one finds applications in the fragrance industry, where it is used as a component in perfumes and flavorings. It can impart sweet, aldehydic, or creamy notes.

Nonan-1-one can be synthesized through various chemical methods, including the oxidation of nonan-1-ol or through Friedel-Crafts acylation reactions. Its physical properties include a boiling point of approximately 194-195 °C and a melting point around -13 °C. It is sparingly soluble in water but miscible with many organic solvents. While generally considered safe for its intended uses in fragrances and flavors at low concentrations, like many organic chemicals, it should be handled with appropriate precautions.
