Ésteres e Derivados
Os ésteres são compostos orgânicos formados pela reação de um ácido (geralmente um ácido carboxílico) com um álcool, liberando água no processo. Sua estrutura química inclui um grupo funcional -COO-, onde um átomo de carbono está ligado a um grupo oxigênio e a um grupo alquila ou arila. Os ésteres possuem uma ampla variedade de aplicações na indústria, incluindo solventes, fragrâncias, aromatizantes e produtos farmacêuticos. No campo farmacológico, alguns ésteres são utilizados como pró-fármacos, pois sua estrutura permite uma liberação controlada ou uma maior biodisponibilidade dos princípios ativos.
Na CymitQuimica, oferecemos ésteres e seus derivados para pesquisa em química orgânica, formulação de fármacos e aplicações industriais.
