AI Product Description
*The following content is generated by AI and is for reference only.
H-Cys(Trt)-2-Chlorotrityl Resin is a specialized solid-phase support widely utilized in the field of peptide synthesis, particularly for the efficient production of cysteine-containing peptides. This reagent features a 2-chlorotrityl chloride resin backbone covalently linked to an L-cysteine molecule where the side-chain thiol group is protected by a trityl (Trt) group. The molecular formula for the active species attached to the resin is typically represented as C37H41ClN2O2S per repeating unit on the polymer matrix, though exact stoichiometry depends on the specific loading capacity of the resin batch. While the free amino acid H-Cys(Trt) possesses a CAS number of 15968-20-6, the resin-bound form does not carry a unique CAS identifier as it is a heterogeneous mixture; however, it is cataloged under various supplier-specific reference numbers.
The primary application of this material lies in Fmoc-based solid-phase peptide synthesis (SPPS). Its distinct advantage over traditional resins like Wang or Rink Amide is its ability to facilitate the cleavage of acid-sensitive peptides under very mild acidic conditions, such as using 1% trifluoroacetic acid (TFA) in dichloromethane. This gentle cleavage protocol is critical when synthesizing complex peptides containing multiple acid-labile protecting groups or sensitive functional moieties that might degrade under standard strong acid cleavage conditions. The trityl protection on the cysteine side chain ensures that the reactive sulfhydryl group remains inert during the coupling cycles, preventing unwanted disulfide bond formation or alkylation side reactions until the final deprotection step.
Upon completion of the peptide assembly, the target sequence is released from the resin with the Trt group intact, allowing for subsequent solution-phase deprotection if necessary. This resin is indispensable for pharmaceutical research and academic laboratories focusing on the synthesis of therapeutic peptides, cyclic peptides, and modified protein fragments where preserving the integrity of the cysteine residue is paramount. Its high stability during storage and ease of handling make it a standard choice for researchers requiring precise control over peptide structure and purity.
