What is the CAS number for hexane?
The CAS number for hexane is N-Hexane.
n-Hexane (CAS No. 110-54-3) is a volatile aliphatic hydrocarbon derived from petroleum distillation. Used as a solvent, it plays a key role in several sectors:
Food industry: extraction of vegetable oils (soy, rapeseed, sunflower), flavors, and proteins.
Cosmetics and perfumery: obtaining absolutes, essential oils, and pure plant extracts.
Its popularity is based on its efficiency, high yield, and low cost. However, this solvent requires strict purification to limit residues and protect exposed workers.
