Isoprene (CAS 78-79-5)

Isoprene (C₅H₈) is a colorless volatile liquid (CAS 78-79-5) with a melting point of -146°C and boiling point 34°C. As a key monomer for synthetic rubber (e.g., polyisoprene, butyl rubber), it is widely used in tires, seals, and biofuels. Highly flammable (flashpoint -48°C) and toxic (rat LC₅₀ 180 g/m³), it requires storage at 0–6°C away from light. Applications span rubber, pharmaceuticals, fragrances, and energy sectors, with market prices influenced by crude oil trends.异戊二烯（C₅H₈）是一种无色易挥发液体，CAS号78-79-5，熔点-146°C，沸点34°C。作为合成橡胶（如聚异戊二烯、丁基橡胶）的核心单体，广泛用于轮胎、密封件及生物燃料生产。 Keywords: Isoprene, Chemical properties, Synthetic rubber, Fine chemicals, Energy and industry, Safety and environment Isoprene (Isoprene) Comprehensive Information 1.
