Grupos Protectores
Los grupos protectores se utilizan en síntesis orgánica para enmascarar temporalmente grupos funcionales reactivos, permitiendo que ocurran reacciones selectivas sin interferencias. Estos grupos son esenciales para los procesos de síntesis en varias etapas, asegurando que partes específicas de la molécula permanezcan no reactivas mientras se realizan otras reacciones. En esta sección, encontrará una variedad de grupos protectores adecuados para diferentes grupos funcionales, junto con reactivos para su introducción y eliminación. En CymitQuimica, ofrecemos una gama completa de grupos protectores de alta calidad para facilitar sus estrategias sintéticas.

CAS: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.Fórmula:C12H15NO5Pureza:Min. 95%Forma y color:PowderPeso molecular:253.25 g/mol2,5-Pyrrolidinedione, 1-(acetyloxy)-
