Gruppi protettivi
I gruppi protettivi sono utilizzati nella sintesi organica per mascherare temporaneamente gruppi funzionali reattivi, consentendo reazioni selettive senza interferenze. Questi gruppi sono essenziali nei processi di sintesi multi-step, assicurando che parti specifiche della molecola rimangano non reattive mentre vengono eseguite altre reazioni. In questa sezione troverai una varietà di gruppi protettivi adatti a diversi gruppi funzionali, insieme a reagenti per la loro introduzione e rimozione. Presso CymitQuimica, offriamo una gamma completa di gruppi protettivi di alta qualità per facilitare le tue strategie sintetiche.

CAS:<p>Fmoc-glycinol is a synthetase that is used to synthesize glycinol conjugates. It binds to the receptor on Gram-positive bacteria and blocks the synthesis of bacterial cell wall, leading to cell death. Fmoc-glycinol has been shown to have high binding constants with amines and an acyl chain, which allows it to bind with antigen. Fmoc-glycinol also has strong nucleophilic properties that allow it to react with chloride ions in water and other polar solvents. This reaction mechanism leads to the formation of a new bond between two molecules, which is called a glycinol linkage.</p>Formula:C17H17NO3Purezza:Min. 95%Colore e forma:White PowderPeso molecolare:283.32 g/molEthylenedithiobis(trimethylsilane) [Protecting Reagent for Aldehydes and Ketones]

CAS:<p>4-tert-Butyl-L-phenylalanine is a synthetically created antigen with the ability to interact with red blood cells. It has been shown to be a potent probe for the detection of P. falciparum, and can be used as an affinity reagent for the isolation and identification of mutations in the c-terminal region of this protein. 4-tert-Butyl-L-phenylalanine also interacts with P. falciparum apical membrane proteins, which are specific to this type of parasite. This interaction may play a role in its invasion into red blood cells, which is what causes malaria infection.</p>Formula:C13H19NO2Purezza:Min. 95%Colore e forma:White PowderPeso molecolare:221.3 g/molN-(2-Pyridyl)bis(trifluoromethanesulfonimide) [Triflating Reagent]

CAS:<p>N-Cbz-L-homoserine is a synthetic amino acid that has been used in positron emission tomography (PET) studies to determine the uptake and utilisation of other amino acids by biological systems. It has also been used in biological studies to investigate the mechanism of nucleophilic attack by serine on Cbz-protected homoserine. N-Cbz-L-homoserine has been shown to have hepatotoxic effects and may be carcinogenic, but no evidence indicates it is mutagenic or teratogenic. It is highly reactive with acrylonitrile, which can cause it to produce hydrogen cyanide as a result of nitrile hydrolysis.</p>Formula:C12H15NO5Purezza:Min. 95%Colore e forma:PowderPeso molecolare:253.25 g/mol2-Mesitylenesulfonyl Chloride
