Applications
Peptide Side Chains: Used as a key intermediate in the synthesis of lipophilic side chains for long-acting peptide drugs (such as Retatrutide, Tirzepatide, and other GLP-1/GIP/Gcg receptor agonists). It incorporates a long-chain fatty acid derivative (C20 diacid), a gamma-glutamic acid spacer, and a mini-PEG (AEEA) linker to extend peptide plasma half-life via albumin binding.
