Catiões Quaternários de Amónio
Nesta seção, você encontrará uma grande variedade de building blocks formados a partir de aminas e que são prontamente solúveis em água. Cátions e sais de amônio quaternário são caracterizados por um átomo de nitrogênio ligado a quatro grupos orgânicos, criando um íon carregado positivamente. Esses compostos são amplamente utilizados em aplicações como desinfetantes, surfactantes e catalisadores de transferência de fase. Sua excelente solubilidade em água e propriedades antimicrobianas os tornam valiosos tanto em ambientes industriais quanto de pesquisa. Na CymitQuimica, oferecemos uma ampla seleção de cátions e sais de amônio quaternário de alta qualidade para atender às suas necessidades.
