description Product Description
Widely used as a solvent in organic synthesis due to its ability to dissolve a variety of compounds without reacting with them. It is particularly favored in the production of pharmaceuticals and fine chemicals, where it helps in the purification and separation processes. In laboratory settings, the chromatographic grade variant is employed as a mobile phase in gas chromatography (GC) and liquid chromatography (LC) owing to its high purity (≥99.9%), low residue, and minimal UV absorbance. Additionally, it serves as an additive in gasoline to enhance octane ratings and reduce engine knocking, improving fuel efficiency and performance. Its low water solubility and high volatility make it suitable for extraction processes in laboratories and industrial applications. However, its use in gasoline has declined in some regions due to environmental and health concerns.
