TCI H0088 Heptane is a straight-chain aliphatic hydrocarbon solvent built on a seven-carbon backbone, supplied as a clear, colourless liquid with strongly nonpolar character. It belongs to the hydrocarbon solvent family and ranks among the most frequently encountered working solvents in chemistry laboratories, pharmaceutical facilities, and instrumental analysis units. Its role is deliberately broad: it serves as an inert reaction medium, an extraction solvent for nonpolar compounds, a mobile-phase component in chromatography, and a rinsing solvent for glassware and surfaces contaminated with oil or grease residues.
The properties that make heptane a preferred choice begin with its very low polarity, which allows it to dissolve nonpolar species such as lipids, oils, and other hydrocarbons that resist more polar media. Equally important is its chemical inertness toward most reagents; heptane does not react readily, so it can be used safely as a medium for reactions that are sensitive to protic solvents. In chromatography, heptane is often selected in place of other hydrocarbon solvents because it delivers comparable elution strength while offering a more controlled evaporation profile, which translates into steadier baselines and more reproducible runs.
In Indonesian laboratories, heptane appears wherever nonpolar extraction, instrumental separation, or thorough degreasing is part of the daily routine — academic research groups, quality control benches in pharmaceutical and chemical plants, and analytical service laboratories alike. Because it is a general-purpose working solvent rather than a specialised reagent, it is typically held as a standing stock item and drawn upon across many different methods within the same facility.
- Nonpolar liquid–liquid extraction: heptane's very low polarity lets it selectively pull lipids, oils, and hydrocarbon analytes out of aqueous or polar matrices with clean phase separation.
- Chromatographic mobile phase: heptane provides elution strength comparable to other hydrocarbon solvents while its more controlled evaporation profile supports steadier, more reproducible separations in normal-phase work.
- Inert reaction medium: because heptane resists reaction with most reagents, it serves as a solvent for chemistry that would be disturbed by protic or otherwise reactive media.
- Glassware and surface rinsing: heptane readily dissolves oil and grease residues, making it an effective final rinse for contaminated glassware and laboratory surfaces before reuse.
- Dissolution of nonpolar compounds: heptane acts as a general dissolving medium for lipids, oils, and other hydrocarbons in sample preparation for downstream chemical or instrumental analysis.

Heptane is highly flammable and its vapour is heavier than air, so it must be handled with that hazard in mind at all times. Store it in a cool, well-ventilated location, ideally inside a dedicated flammable-solvent cabinet, and keep containers tightly closed to limit evaporative loss and vapour accumulation at floor level. Use the original manufacturer container or a compatible, properly labelled solvent bottle; avoid open vessels. Dispense and work with heptane inside a fume hood, away from open flames, hot surfaces, and sources of sparks or static discharge. Wear appropriate gloves, safety glasses, and a laboratory coat, and collect used solvent as organic waste rather than discharging it to the drain.
