gamma-Benzyl L-glutamate Chemical Properties,Usage,Production

Chemical Properties

white powder

Uses

L-Glutamic acid γ-benzyl ester is commonly used in the synthesis of polymers for biological applications. Some of the examples are:

  • Synthesis of bioreducible block copolymers based on poly(ethylene glycol) and poly(γ-benzyl L-glutamate) for Intracellular drug delivery.
  • Synthesis of biodegradable poly(L-glutamic acid)-b-polylactide for magnetic resonance imaging (MRI)-visible drug delivery system.
  • Synthesis of pH and temperature-responsive diblock copolymers based on poly(L-glutamic acid).

reaction suitability

reaction type: solution phase peptide synthesis

Purification Methods

Recrystallise the ester from H2O and store it at 0o. [Estrin Biochemical Preparations 13 25 1971, Beilstein 6 IV 2538.]
