Grupos de protecção
Os grupos de proteção são usados na síntese orgânica para mascarar temporariamente grupos funcionais reativos, permitindo que reações seletivas ocoam sem interferência. Esses grupos são essenciais para processos de síntese em várias etapas, garantindo que partes específicas da molécula permaneçam não reativas enquanto outras reações são realizadas. Nesta seção, você encontrará uma variedade de grupos de proteção adequados para diferentes grupos funcionais, juntamente com reagentes para sua introdução e remoção. Na CymitQuimica, oferecemos uma gama abrangente de grupos de proteção de alta qualidade para facilitar suas estratégias sintéticas.

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.Fórmula:C13H16N2O5Pureza:Min. 95%Cor e Forma:PowderPeso molecular:280.28 g/mol(9H-Fluoren-9-yl)methyl (perfluorophenyl) carbonate
