Undecane(CAS: 1120-21-4)

Undecane is a saturated hydrocarbon with the chemical formula C11H24. It is a colorless, odorless liquid that is insoluble in water but miscible with organic solvents. As a straight-chain alkane, undecane exhibits low reactivity and is primarily used as a solvent and in research applications. Its physical properties include a high boiling point (around 194°C) and a density slightly greater than water.

Undecane is commonly used in pharmaceuticals as a solvent for lipid-based compounds. In industrial settings, it serves as a component in the production of specialty chemicals, lubricants, and fuel additives. It is also employed in food science as a flavoring agent and in research for studying hydrocarbon behavior. Additionally, undecane is used in calibration standards for analytical instruments.

Undecane is generally considered safe when handled properly, with low toxicity and minimal health risks. However, prolonged inhalation or skin contact may cause irritation. Safety data sheets (SDS) classify it as non-hazardous under normal conditions, but users should wear protective gloves and ensure adequate ventilation. It is not considered a carcinogen or mutagen in standard assessments.

Undecane should be stored in a cool, dry place (ideally 0-25°C), away from direct light and heat sources. Use sealed, airtight containers made of materials like glass or stainless steel to prevent evaporation and contamination. Maintain low humidity levels to avoid degradation. Ensure proper labeling and store away from incompatible substances such as strong oxidizers.
