Protecting Groups
Protecting groups are used in organic synthesis to temporarily mask reactive functional groups, allowing selective reactions to occur without interference. These groups are essential for multi-step synthesis processes, ensuring that specific parts of the molecule remain unreactive while other reactions are performed. In this section, you will find a variety of protecting groups suitable for different functional groups, along with reagents for their introduction and removal. At CymitQuimica, we offer a comprehensive range of high-quality protecting groups to facilitate your synthetic strategies.

CAS:Boc-L-aspartic acid a-9-fluorenylmethyl ester is a synthetic compound that mimics the structure of acetylcholine. It has been shown to be an efficient method for generating pseudopeptides and cyclic peptides. This compound may be used as a surrogate for acetylcholine in virus research, since it can bind to the same receptor. Boc-L-aspartic acid a-9-fluorenylmethyl ester has also been used to generate monoclonal antibodies that are neutralizing against foot-and-mouth disease viruses.Formula:C23H25NO6Purity:Min. 97 Area-%Molecular weight:411.45 g/molHydrogen Chloride (ca. 4mol/L in 1,4-Dioxane)
