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:Trityl-L-phenylalanine diethylamine is a reagent that is used in the synthesis of peptides, reagents, and other chemicals. Trityl-L-phenylalanine diethylamine reacts with an azide to form a triazole. It can also be used to convert an acid into an amino acid. This chemical has been shown to be sensitive to plasmin, which may lead to degradation during peptide synthesis.Fórmula:C28H25NO2·C4H11NPureza:Min. 95%Cor e Forma:PowderPeso molecular:480.64 g/molBenzyl Isopropenyl Ether [Hydroxyl-Protecting Agent]

CAS:Fmoc-N-Me-Asn(Trt)-OH is a peptidomimetic that mimics the sequence of the serine protease. The Fmoc group on the N-terminal amino acid is used to protect against proteolytic degradation and its methyl ester group confers stability in biological fluids. The Fmoc-N-Me-Asn(Trt)-OH has been shown to have minimal effects on endogenous protein synthesis, while also being quantified with high sensitivity and specificity. This compound has been shown to inhibit protein-protein interactions by acting as a competitive inhibitor of serine proteases.Fórmula:C39H34N2O5Pureza:Min. 95%Cor e Forma:PowderPeso molecular:610.7 g/molChlorodimethylphenylsilane
