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: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.Formula:C12H15NO5Purity:Min. 95%Color and Shape:PowderMolecular weight:253.25 g/mol2,5-Pyrrolidinedione, 1-(acetyloxy)-
