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:Fmoc-L-Cys(StBu)-OH is a synthetic molecule that is used in pharmaceutical formulations. It can be synthesized from Fmoc-L-Cys and L-serine methyl ester by the chemical ligation of the two molecules. The chloride group at the end of this molecule provides a functional group for conjugation with other biomolecules, such as fatty acids. This molecule has been shown to have high purity with an isolated yield of about 98%.Formula:C22H25NO4S2Purity:Min. 98 Area-%Color and Shape:PowderMolecular weight:431.57 g/molAllyltriethylsilane

CAS:Boc-L-prolinal is a stereoselective enolate that has been used in the synthesis of organometallic compounds. It is also used in the preparation of monoclonal antibodies, which are proteins that are produced by the immune system to help fight off infections. Boc-L-prolinal has been shown to be an effective agent for treating many cancers, including breast cancer and melanoma. In addition, it has been shown to inhibit epidermal growth factor (EGF) and other growth factors, which may be due to its ability to induce apoptotic signaling. Boc-L-prolinal also contains a carbonyl group, which can undergo acidolysis reactions with nucleophiles such as water or alcohols.Formula:C10H17NO3Purity:Min. 95%Color and Shape:Colorless Clear LiquidMolecular weight:199.25 g/molN-(9-Fluorenylmethoxycarbonyloxy)succinimide
