AI Product Description
*The following content is generated by AI and is for reference only.
Fmoc-Val-Wang resin is a specialized solid-phase synthesis support widely utilized in the field of peptide chemistry for the efficient construction of complex polypeptides. This reagent consists of valine, an essential amino acid, chemically linked to a Wang resin matrix via a stable amide bond, with the N-terminal protected by a fluorenylmethyloxycarbonyl (Fmoc) group. The molecular formula for the active Fmoc-Val moiety attached to the linker is C21H24N2O5, though the complete resin structure varies slightly depending on the specific loading capacity and cross-linking density of the polymer backbone, typically polystyrene-divinylbenzene. While the exact CAS number is often associated with the free acid form or specific derivatives rather than the resin-bound complex itself, the constituent Fmoc-valine component generally carries the identifier 13809-76-8.
The primary application of Fmoc-Val-Wang resin lies in automated and manual solid-phase peptide synthesis (SPPS). It serves as an ideal starting point for synthesizing peptides requiring a C-terminal carboxylic acid functionality. During the synthesis process, amino acids are sequentially added to the resin-bound valine using standard coupling reagents. The Fmoc protecting group ensures orthogonal stability, allowing removal under mild basic conditions like piperidine without affecting the acid-labile linkage to the Wang resin. Once the desired peptide sequence is assembled, the final cleavage step utilizes strong acidic conditions, such as trifluoroacetic acid (TFA), which simultaneously removes all side-chain protecting groups and releases the full-length peptide from the resin support. The Wang linker facilitates this release by yielding the free carboxylic acid at the C-terminus, making it indispensable for producing therapeutic peptides, diagnostic markers, and research tools in biochemistry and pharmaceutical development. Its high loading capacity and robustness against various reaction conditions make it a preferred choice for researchers aiming to synthesize valine-containing sequences with high purity and yield.
