一般說明

3-Methyl-1-pentyn-3-ol acts as initiator during the synthesis of propargyl-terminated polylactide by bulk ring-opening polymerization.

應用

3-Methyl-1-pentyn-3-ol is propargyl alcohol that can be used as:
  • A reactant to synthesize α-methylene cyclic carbonates by reacting with carbon dioxide.
  • A reactant in the synthesis of 2,6,9-trisubstituted purine based CDK inhibitors.
  • An initiator in the synthesis of polylactide bearing terminal propargyl group via ring-opening polymerization of L-lactide.

生化／生理作用

3-Methyl-1-pentyn-3-ol is a sedative and induces hepatic P4503A in mouse.

A titrimetric method is described for the determination of three acetylenic hypnotics, namely ethchlorvynol, ethinamate, and methylpentynol carbamate, in bulk and in dosage forms. The method involves the use of either 1,3-dibromo-5,5-dimethylhydantoin (DBH), N-bromosuccinimide (NBS) or N-bromophthalimide (NBP) as titrants.
