Background information

An excellent building block for the preparation of phosphotyrosine-containing peptides [1]. This derivative can be introduced using standard activation methods, such as PyBOP® and TBTU. Using this reagent, even peptides containing multiple phosphorylation sites have been prepared efficiently by standard Fmoc SPPS methods [1].

The product number for this product was previously 04-12-1156.
