Z-Gln(Trt)-OH
Request a Quote
Z-Gln(Trt)-OH is a trityl- and carbobenzoxy-protected form of L-glutamine used in peptide synthesis strategies where side-chain protection is critical. The combination of Trt for the amide group and Z for the N-terminus prevents premature deprotection, making it ideal for assembling glutamine-containing sequences in both solution and solid-phase approaches.
