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.
