Phosphorylation, particularly on tyrosine residues, is a cornerstone of cellular communication. These modifications act as critical switches in signal transduction pathways, influencing everything from cell growth to immune responses. For scientists delving into the intricacies of these processes, a reliable supply of specialized building blocks is paramount. This is where compounds like N-Fmoc-O-benzyl-L-phosphotyrosine (CAS 191348-16-0) become indispensable tools.

As a leading manufacturer and supplier of high-quality chemical intermediates, we understand the demands of modern research. N-Fmoc-O-benzyl-L-phosphotyrosine is meticulously synthesized to ensure high purity, typically ≥99%. This purity is not just a number; it's a guarantee of reliability for complex peptide synthesis and biochemical studies. Researchers looking to buy this crucial component are often focused on replicating natural phosphorylation events to understand disease mechanisms or develop novel therapeutics.

The unique structure of N-Fmoc-O-benzyl-L-phosphotyrosine allows it to effectively mimic phosphorylated tyrosine residues. This makes it an ideal choice for constructing phosphopeptide libraries. These libraries are invaluable for screening protein-protein interactions, identifying substrates for kinases and phosphatases, and exploring drug targets. For instance, in cancer research, understanding the aberrant tyrosine phosphorylation that drives tumor growth is a key objective. By using this phosphotyrosine derivative, scientists can create synthetic peptides that mimic these aberrant states, providing insights into disease progression and potential intervention points.

Furthermore, the Fmoc protecting group facilitates its straightforward incorporation into solid-phase peptide synthesis, a standard technique in laboratories worldwide. The benzyl ester serves as a protective group for the phosphate, which can be strategically removed later in the synthesis. This synthetic flexibility is crucial for building complex biomolecules with precise modifications.
