Xylene is an organic compound with the chemical formula C₈H₁₀ and CAS Number 1330-20-7 for mixed Xylene isomers. It is commonly supplied as a colourless, volatile liquid with a characteristic aromatic odour. It is practically insoluble in water but miscible with many organic solvents, making it a useful solvent for laboratory and chemical applications.

Xylene is valued for its solvent properties and ability to dissolve a wide range of organic compounds, resins, oils, and other substances. Common laboratory applications include tissue processing, histological slide preparation, sample preparation, chemical extraction, chromatography, and analytical chemistry procedures. It is particularly used as a clearing agent in histology and microscopy, where it helps remove alcohol from tissue samples before mounting.

Its solvent compatibility, relatively high solvency, and chemical stability make Xylene useful in analytical chemistry, pathology laboratories, histology, organic chemistry, and general laboratory research. It may also be used in specialised chemical formulations, paint and coating research, and industrial processes requiring an aromatic hydrocarbon solvent. The appropriate isomer, 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: Xylene is a flammable liquid and vapour. Exposure may cause skin and eye irritation, dizziness, drowsiness, and respiratory irritation. Prolonged or repeated exposure may affect the central nervous system and other organs. Avoid inhalation of vapours and direct skin contact. Handle it in a suitable, well-ventilated area or chemical fume hood using appropriate personal protective equipment, including chemical-resistant gloves, protective clothing, and safety goggles. 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.
