Lactonas
As lactonas são uma classe de ésteres caracterizadas por uma estrutura cíclica formada através da esterificação intramolecular de ácidos hidroxílicos. Estes compostos são conhecidos por suas estruturas em anel distintas, que podem variar de três a sete ou mais membros. As lactonas são amplamente utilizadas na indústria de sabores e fragrâncias devido aos seus aromas agradáveis, bem como em produtos farmacêuticos e agroquímicos por suas diversas atividades biológicas. Na CymitQuimica, oferecemos uma seleção abrangente de lactonas de alta qualidade para apoiar suas aplicações de pesquisa e industriais, garantindo desempenho confiável e eficaz em seus projetos.
