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:Cbz-L-glutamine is a water soluble compound that is used in the synthesis of pomalidomide. It is synthesized through a stepwise amide formation from methylamine and ethylene diamine. Cbz-L-glutamine has been shown to have an inhibitory effect on cancer cells, which may be due to its ability to break down hydroxamic acids. This chemical reaction causes the release of hydrogen ions, which leads to the disruption of various cellular processes, such as DNA replication and protein synthesis. The uptake of Cbz-L-glutamine by cancer cells has been shown in tissue culture experiments.Formula:C13H16N2O5Purity:Min. 95%Color and Shape:PowderMolecular weight:280.28 g/mol(9H-Fluoren-9-yl)methyl (perfluorophenyl) carbonate
