Cyclobutanone CAS 1191-95-3

① Acts Cyclobutanone as a key four-membered ring building block for organic synthesis, constructing cyclobutyl ketone skeletons in pharmaceutical and agrochemical molecule production.
② Serves Cyclobutanone CAS 1191-95-3 as a cycloaddition reaction reagent, participating in [2+2] cycloaddition to synthesize spirocyclic and polycyclic compounds in fine chemical processing.
③ Functions as a polymer monomer and modifier, preparing high-performance cyclic polymers with unique mechanical properties in polymer manufacturing.

Store Cyclobutanone CAS 1191-95-3 at 0-10℃ in sealed amber glass/HDPE drums under inert gas in cool, fire-proof, well-ventilated area, away from open fire, heat sources, strong oxidants and direct sunlight. Wear nitrile gloves, safety goggles and vapor mask; avoid vapor inhalation, skin/eye contact & ingestion (mild irritant). Reseal tightly post-use to prevent volatilization and oxidation. Dispose via licensed waste channels; transport as flammable liquid, leak-proof & explosion-proof packaging, cold chain optional, avoid high-temp/impact and oxidant mixing.
