Butyl n-Octanoate TCI O0029

Butyl n-Octanoate from TCI (product code O0029, CAS 589-75-3) is the ester of n-octanoic acid and n-butanol. It is a medium-chain fatty acid ester with a simple aliphatic structure. Flavor and fragrance research knows it for its fruity notes, and it often appears as a volatile component in natural and fermented products. In the laboratory it serves as a building block, an analytical reference compound, and a model substrate for studying ester reactions, which suits both synthetic and analytical work.

Researchers choose butyl octanoate because its structure is clear and simple, it is hydrophobic, and it is volatile enough to analyze by gas chromatography. It belongs to the homologous series of octanoate esters, so researchers can use it to compare how the length of the alcohol chain affects physical properties, retention time, and aroma. The ester group stays stable under normal storage but can still be hydrolyzed in a controlled way. This makes the compound useful for enzyme and catalysis research, where a predictable and well-defined substrate matters for reproducible results.

In Indonesia, this ester is useful to food analysis laboratories, flavor research laboratories, biotechnology laboratories studying lipase enzymes, and energy laboratories working with fatty acid esters. University research groups, quality control units, and industrial R&D facilities can use it as a reference standard for chromatographic methods, as a model compound in teaching and research on esterification and hydrolysis, and as a starting material for synthetic studies of non-heterocyclic aliphatic compounds.

• Gas chromatography reference standard: it is volatile and structurally simple, so it works well for calibrating retention times and identifying volatile ester components in food and fermentation samples.
• Flavor and aroma research: it contributes fruity notes, so flavor laboratories can use it to study how volatile esters shape the sensory profile of natural and fermented products.
• Lipase and esterase enzyme studies: its ester group can be hydrolyzed in a controlled way, so it serves as a well-defined model substrate for measuring enzyme activity and selectivity.
• Homologous series comparison studies: as one of the octanoate esters, it helps researchers compare how alcohol chain length affects physical properties, chromatographic behavior, and aroma.
• Organic synthesis building block: its simple aliphatic ester structure makes it a convenient non-heterocyclic starting material or model compound for studying esterification, transesterification, and hydrolysis reactions.

Store Butyl n-Octanoate in its original, tightly sealed container, in a cool, dry, well-ventilated area away from direct sunlight, heat sources, and ignition sources. Keep it away from strong oxidizing agents, strong acids, and strong bases, which can promote unwanted hydrolysis or other reactions. Glass or other chemically compatible containers are recommended. Handle the material in a fume hood or well-ventilated area. Wear standard personal protective equipment, including safety glasses, chemical-resistant gloves, and a laboratory coat. Avoid inhaling vapors and contact with skin and eyes. Always read the TCI Safety Data Sheet before use, and dispose of waste according to local regulations.
