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.
