  • Applications

    2-Ethyl-4-methylphenol (CAS 3855-26-3) is used primarily as a chemical intermediate and fragrance-building block; it serves as an odorant and component for fragrance ingredients, as a precursor for pharmaceutical and agrochemical intermediates, and as a starting point for the synthesis of dyes and pigments; it can also act as a building block for specialty polymers and coatings formulations, with applications and limits governed by synthetic routes and local regulatory requirements.
