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)

CAS:Boc-glu(OBzl)-OH is a small-molecule drug that binds to the glutamate receptor. It has been shown to have anticancer activity in vitro and in vivo, but does not affect normal cells. Boc-glu(OBzl)-OH has been used as a synthetic substrate for the preparation of conjugates containing an amide group. This chemical can also be used as an anticancer agent by inhibiting protease activity, which inhibits cancer cell growth. The uptake of Boc-glu(OBzl)-OH can be increased by making it more acidic or by using an efficient method such as ultrasound.Formula:C17H23NO6Purity:Min. 98 Area-%Color and Shape:PowderMolecular weight:337.37 g/mol2-(Benzyloxy)-1-methylpyridin-1-ium trifluoromethanesulfonate
