AI Product Description
*The following content is generated by AI and is for reference only.
H-Tyr(tBu)-2-Chlorotrityl Resin is a specialized solid-phase support widely utilized in peptide synthesis and combinatorial chemistry. This reagent consists of the amino acid L-tyrosine, protected at the phenolic hydroxyl group with a tert-butyl (tBu) moiety, covalently attached to a 2-chlorotrityl chloride resin matrix via an ester linkage. The molecular formula for the active site on the resin is complex due to the polymeric nature of the support, but the key structural unit corresponds to C18H19ClO3 for the linker-amino acid conjugate before attachment. While the resin itself does not possess a single CAS number as it is a heterogeneous mixture, the precursor 2-chlorotrityl chloride resin is often cataloged under specific manufacturer identifiers, and the free acid H-Tyr(tBu)-OH has the CAS number 1564-73-0.
The primary utility of this product lies in its ability to facilitate the efficient synthesis of peptides containing tyrosine residues while maintaining the integrity of the side chain. The tBu protecting group ensures that the phenolic hydroxyl remains inert during standard coupling reactions using Fmoc or Boc strategies, preventing unwanted side reactions such as oxidation or alkylation. A distinct advantage of the 2-chlorotrityl linker is its mild cleavage profile. Unlike harsh acid conditions required for other linkers, this resin allows for the release of the peptide using very weak acids, such as 1% trifluoroacetic acid (TFA) in dichloromethane. This gentle cleavage mechanism is critical for preserving acid-labile modifications or for synthesizing sensitive fragments without degrading the backbone.
Researchers frequently employ H-Tyr(tBu)-2-Chlorotrityl Resin in fragment condensation approaches, where small, protected peptide segments are synthesized separately and then ligated together. Its compatibility with automated synthesizers makes it a staple in pharmaceutical laboratories developing novel therapeutics, including hormone analogs and antimicrobial peptides. Furthermore, the high loading capacity and stability of the trityl linker ensure consistent yields and purity, making it an indispensable tool for modern medicinal chemistry and proteomics research aiming to produce complex biological molecules with precision.
