Boc-pGlu-OEt (N-Boc-L-pyroglutamic acid ethyl ester, also known as Boc-Pyr-OEt or ethyl (S)-1-Boc-5-oxopyrrolidine-2-carboxylate) is a protected L-pyroglutamic acid derivative. The molecule features a pyroglutamic acid core — a cyclic amino acid formed by intramolecular cyclization of glutamic acid — with a tert-butyloxycarbonyl (Boc) group protecting the ring nitrogen and an ethyl ester protecting the carboxylic acid.

Z-Trp(Boc)-OH.DCHA (Nα-Z-Nᶦⁿ-Boc-L-tryptophan dicyclohexylammonium salt) is a doubly protected L-tryptophan derivative featuring two orthogonal protecting groups. The molecule consists of an L-tryptophan core with a carbobenzoxy (Z) group protecting the α-amino functionality and a tert-butyloxycarbonyl (Boc) group protecting the indole side chain nitrogen.

Boc-D-Phe-OH (N-α-tert-Butoxycarbonyl-D-phenylalanine) is a protected D-phenylalanine derivative featuring a tert-butyloxycarbonyl (Boc) group attached to the α-amino functionality. The molecule consists of a D-configuration phenylalanine core — a chiral amino acid with a benzyl side chain — with the Boc protecting group shielding the amino group from unwanted side reactions.

GS-650804 / Boc-(S)-cyclopropylglycine (N-[(1,1-dimethylethoxy)carbonyl]-(S)-amino-cyclopropylacetic acid) is a Boc-protected non-natural amino acid featuring a cyclopropyl group at the α-carbon of the glycine scaffold. This unique structural motif combines the sterically constrained cyclopropyl ring with the chirality of the (S)-configuration, creating a conformationally locked amino acid analogue that is highly valued in medicinal chemistry and peptide research.

Boc-His(Trt)-Ala-OH (N-[(1,1-dimethylethoxy)carbonyl]-1-(triphenylmethyl)-L-histidyl-L-alanine) is a protected dipeptide building block featuring a Boc-protected histidine residue at the N-terminus with a trityl (Trt) group on the imidazole side chain, coupled to an alanine residue at the C-terminus.

Pal-Lys(Boc)-OH (N-[(1,1-dimethylethoxy)carbonyl]-L-lysine palmitoyl ester) is a specialized amino acid derivative featuring a lysine backbone with dual modifications: a tert-butyloxycarbonyl (Boc) protecting group on the α-amino functionality and a palmitoyl (hexadecanoyl) ester group on the side-chain carboxyl.
