Applications

4-Methyl-1-pentyne, is used as a polymer matrix together with synthesized NH2-MIL 53 metal organic framework (MOF) as a filler were used to fabricate a mixed matrix membrane (MMM). It is also used in addition reactions which are typical in alkyne reactions such as halogenation, hydrogenation, hydrohalogenation, hydration, oxidative cleavage, nitrile formation and acidity of terminal alkynes. Polymerisation and substitution reactions are also useful in chemical synthesis.

Notes

Stable under normal temperatures and pressures. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Keep away from oxidizing agents.
