n-Pentane is an organic compound with the chemical formula C₅H₁₂ and CAS Number 109-66-0. It is commonly supplied as a colourless, highly volatile liquid with a characteristic petroleum-like odour. It is practically insoluble in water but miscible with many non-polar organic solvents, making it a useful solvent for laboratory and chemical applications.

n-Pentane is valued for its non-polar solvent properties and ability to dissolve oils, fats, waxes, and various organic compounds. Common laboratory applications include liquid-liquid extraction, sample preparation, chromatography, solvent purification, lipid analysis, and analytical chemistry procedures. It is also used in research involving hydrocarbon properties, solvent systems, and organic compound separation.

Its low polarity, low boiling point, and high volatility make n-Pentane useful in analytical chemistry, organic chemistry, petroleum research, and general laboratory applications. It may also be used in specialised chemical formulations, polymer research, and industrial processes requiring a highly volatile non-polar hydrocarbon solvent. The appropriate grade and purity should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: n-Pentane is an extremely flammable liquid and vapour. Its vapours may form explosive mixtures with air and can travel to distant ignition sources. It may cause drowsiness and dizziness if inhaled, while aspiration into the lungs if swallowed may cause serious or fatal injury. Handle it in a suitable, well-ventilated area using appropriate personal protective equipment. Keep it away from heat, sparks, open flames, and other ignition sources. Store in a tightly closed container in a cool, well-ventilated area and follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
