Cetonas
Las cetonas son compuestos orgánicos caracterizados por la presencia de un grupo carbonilo (C=O) unido a dos átomos de carbono. Estos compuestos son altamente versátiles y juegan un papel crucial en diversas reacciones químicas, incluyendo oxidación, reducción y condensación. Las cetonas son intermediarios esenciales en la síntesis de productos farmacéuticos, fragancias y polímeros. En CymitQuimica, ofrecemos una amplia gama de cetonas de alta calidad para apoyar sus aplicaciones de investigación e industriales.
