About Isopentane, 99%

Isopentane is a laboratory solvent (Synthesis grade) carrying the CAS registry number 78-78-4, specified at 99% purity. Formula C5H12, molecular weight 72.15 g/mol. Systematically, it is named 2-methylbutane. Alternative names: Isoamylhydride and Butane, 2-methyl-.

The material typically appears as a colourless liquid. Key physical data: a density of 0.62 g/ml. Keep containers tightly closed in a cool, well-ventilated area away from heat and ignition sources. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include reaction medium, extraction and work-up and cleaning and rinsing. It is used across academic and industrial research and pharmaceutical manufacturing.

Standard pack sizes are 500 mL, 5 L, 4 x 25 kg and 160 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
