AI Product Description
*The following content is generated by AI and is for reference only.
H-Trp-2-Chlorotrityl Resin is a specialized solid-phase synthesis reagent widely utilized in peptide chemistry for the efficient assembly of complex polypeptides. This product consists of tryptophan (Trp) covalently attached to a 2-chlorotrityl chloride resin support via a stable ester linkage. The chemical structure features an indole side chain characteristic of tryptophan, protected by a hydrogen atom at the N-terminus, making it ready for subsequent coupling reactions without requiring additional protecting group strategies on the amine functionality.
The molecular formula of the active amino acid moiety is C11H12N2O2, while the complete resin system incorporates this unit onto a polystyrene-divinylbenzene matrix functionalized with chlorotrityl groups. Although the resin itself does not possess a single CAS number due to its polymeric nature, the specific H-Trp derivative often relates to precursor CAS identifiers associated with N-Fmoc-Tryptophan or similar protected forms used in its preparation. Its primary application lies in automated and manual solid-phase peptide synthesis (SPPS), particularly for the C-terminal amidation or acid-labile protection strategies.
The 2-chlorotrityl linker offers distinct advantages over traditional Wang resins. It allows for the release of the final peptide under mild acidic conditions using dilute trifluoroacetic acid (TFA) in dichloromethane, preserving sensitive side-chain protecting groups that might otherwise be cleaved prematurely. This feature is crucial when synthesizing peptides containing base-sensitive residues or those requiring orthogonal protection schemes. Tryptophan, being one of the twenty standard amino acids, plays a vital role in protein structure and function, influencing hydrophobic interactions and fluorescence properties. Consequently, H-Trp-2-Chlorotrityl Resin serves as an essential building block for pharmaceutical research, enabling the rapid production of therapeutic candidates, diagnostic agents, and biochemical probes. Researchers favor this resin for its high loading capacity, excellent stability during synthesis cycles, and ease of purification. By facilitating precise control over peptide sequence and stereochemistry, this material significantly accelerates drug discovery pipelines and fundamental biological studies involving protein-peptide interactions.
