trans-2-Nonen-1-ol TCI N0587

trans-2-Nonen-1-ol is a nine-carbon allylic alcohol. Its carbon-carbon double bond has the trans (E) configuration and sits at the second carbon, right next to a primary hydroxyl group. It is the geometric isomer counterpart of cis-2-nonen-1-ol. In the laboratory it works as a non-heterocyclic building block for organic synthesis. It is also well known in flavour and fragrance chemistry, so it is often used as an analytical reference compound to identify volatile components in many kinds of sample matrices.

The main reason chemists choose this material is its clearly defined trans geometry. Trans isomers are generally more thermodynamically stable than cis isomers. Many stereospecific reactions of allylic alcohols give products whose configuration depends on the starting geometry of the double bond. Using a clearly defined isomer lets researchers control the stereochemistry of products from reactions such as asymmetric epoxidation, addition, or rearrangement. The primary hydroxyl group is also easy to convert into esters, ethers, halides, or aldehydes. This makes the compound a flexible starting point for longer synthetic routes.

For laboratories in Indonesia, this compound is useful in food technology research, essential oil analysis, and synthetic organic chemistry. University research groups can use it as a model substrate for studying stereoselective transformations of allylic alcohols. Analytical laboratories can use it as a reference standard when they characterise aroma profiles of natural products and processed foods. Its dependable isomeric identity supports reproducible work in both teaching and research settings, where clear, comparable results matter for publications, theses, and quality evaluations.

• Stereoselective synthesis studies: the defined trans (E) double bond next to the primary alcohol makes it a good substrate for exploring how starting alkene geometry controls product configuration.
• Asymmetric epoxidation research: as an allylic alcohol with known geometry, it suits investigations of epoxidation reactions where the hydroxyl group directs the reaction and the alkene configuration sets product stereochemistry.
• Functional group derivatisation: the primary hydroxyl group can readily be converted into esters, ethers, halides, or aldehydes, which lets chemists prepare a range of nine-carbon unsaturated intermediates.
• Flavour and aroma analysis: its recognised role in flavour and fragrance chemistry makes it a helpful analytical reference compound for identifying volatile components in food and natural product samples.
• Essential oil characterisation: laboratories profiling volatile constituents of essential oils can use it as a comparison standard, which helps them assign peaks and confirm the identity of related unsaturated alcohols.

Keep trans-2-Nonen-1-ol in its original, tightly closed container, in a cool, dry, well-ventilated area away from heat, sparks, open flames, and direct sunlight. Store it apart from strong oxidising agents. Because it is an unsaturated alcohol, reclose the container promptly after each use to limit exposure to air and moisture. Handle the material in a fume hood and wear suitable protective gloves, safety glasses, and a laboratory coat. Do not inhale vapours, and avoid contact with skin and eyes. Always read the manufacturer's safety data sheet before use, and dispose of residues according to local laboratory waste regulations.
