noctanol

Noctanol is not a recognized, defined chemical name in major chemical databases or standard nomenclature. As a term, it may appear as a misnomer or informal nickname for other nine-carbon alcohols (such as nonanol) or for one of the octanol/nonanol isomer groups. It can also be encountered in fictional contexts, branding, or in amateur reporting, where it does not correspond to a defined substance.

If noctanol is intended to refer to nonanol, the reference would be to a nine-carbon primary alcohol with the general formula C9H19OH. There are several nine-carbon alcohol isomers (nonanol and nonyl alcohol isomers), and different structural forms (primary, secondary, tertiary) can lead to varying properties and odors. Because “noctanol” is not a precise structural descriptor, exact identity depends on the intended isomer.

In general, long-chain aliphatic alcohols share certain characteristics: they are typically colorless liquids or solids at room temperature, have relatively high boiling points, are soluble in organic solvents, and are immiscible with water to a large extent. They are flammable and can be irritants to skin or eyes, with safety profiles depending on the specific isomer.

Uses for real nine-carbon or longer-chain alcohols include solvents, intermediates in chemical synthesis, plasticizers, and components in fragrances or flavorings. When used in perfumery, larger-chain alcohols can contribute fatty, waxy, or bready notes, among others. Due to the ambiguity of the term, no specific properties or safety data can be provided for noctanol without a defined structure.
