Cetonas C17 +
Las cetonas C17+ son compuestos orgánicos que contienen un grupo carbonilo (C=O) unido a cadenas de carbono con diecisiete o más átomos. Estas cetonas de cadena larga se utilizan en la producción de surfactantes, lubricantes y productos químicos especializados. También sirven como intermediarios valiosos en la síntesis de moléculas orgánicas complejas. En CymitQuimica, ofrecemos una amplia selección de cetonas C17+ de alta calidad para satisfacer sus necesidades sintéticas e industriales.
