Pentadecane from TCI (product code P0606) is a straight-chain alkane with fifteen carbon atoms. It belongs to the saturated hydrocarbons, a class of compounds that is strongly nonpolar and has low chemical reactivity. In the laboratory, pentadecane serves as a reference compound in hydrocarbon analysis and as an internal standard in gas chromatography. It is also used as a high-boiling nonpolar solvent and as a model substance in research on fuels, lubricants and phase change materials for heat storage. It is listed under Non-Heterocyclic Building Blocks.
The main reason laboratories choose this material is its chemical stability. As a saturated alkane, pentadecane has no reactive functional groups, so it stays inert in most reaction and analytical systems. This makes it a good standard because it does not interfere with the measurement. Its volatility is low and its gas chromatography retention time is well defined, so it works as a dependable marker within the n-alkane series. At tropical room temperature it is generally a clear liquid. Its melting and freezing behaviour close to room temperature also makes it of interest for thermal energy storage studies.
In Indonesian laboratories, pentadecane is widely needed by petroleum and petrochemical testing laboratories. These labs use it as a reference compound when characterising hydrocarbon fractions and checking chromatographic performance. Environmental laboratories that monitor hydrocarbon pollutants also rely on it as a well-characterised alkane standard for consistent quantification. Research groups working on fuels, lubricants and thermal energy storage materials value it as a simple, well-defined model compound for controlled experiments and method development.
- Gas chromatography internal standard: pentadecane is chemically inert and has a clearly defined retention time, so it allows accurate quantification without reacting with or interfering with the target analytes.
- Hydrocarbon analysis reference: as a member of the n-alkane series, it is a dependable marker for identifying and comparing hydrocarbon fractions in petroleum and petrochemical samples.
- High-boiling nonpolar solvent: its low volatility and lack of reactive functional groups make it suitable for dissolving nonpolar substances in work that must avoid solvent evaporation or side reactions.
- Fuel and lubricant model studies: as a simple, well-defined straight-chain alkane, it lets researchers study the behaviour of hydrocarbon fuels and lubricants under controlled, reproducible conditions.
- Phase change material research: its melting and freezing behaviour near room temperature makes it a useful model compound for studying thermal energy storage and heat management materials.

Store pentadecane in its original tightly sealed container, or in a compatible glass or chemical-resistant container. Keep it in a cool, dry, well-ventilated area away from heat sources, open flames and strong oxidising agents. Because it is a hydrocarbon, it should be treated as a combustible organic material. Wear the usual laboratory protective equipment, including safety glasses, chemical-resistant gloves and a lab coat. Handle it in a well-ventilated area or a fume hood, avoid prolonged skin contact and inhaling vapour, and clean up spills promptly with suitable absorbent material. Always check the supplier's Safety Data Sheet for detailed hazard and disposal information.
