Description

o-Cymene (CAS NO 527-84-4) is a key aromatic hydrocarbon and a valuable isomer of cymene, prized for its role as a versatile chemical intermediate and solvent. Its high volatility makes it particularly effective in applications requiring rapid evaporation and efficient solvency. This compound is essential for manufacturers in the fragrance, agrochemical, and pharmaceutical industries seeking reliable, high-purity raw materials for synthesis and formulation.

Application

• Fragrance and Flavor Industry: Used as a solvent and as a starting material for the synthesis of aroma chemicals and perfumery ingredients.
• Agrochemical Synthesis: Serves as a key intermediate in the production of pesticides, herbicides, and other crop protection agents.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Industrial Solvent: Acts as an effective solvent for resins, oils, and other organic compounds in coatings and cleaning formulations.
• Chemical Research & Development: Utilized as a reagent and building block in organic synthesis and material science research.
• Production of p-Cymene and Cresols: A precursor in the isomerization to p-cymene and subsequent oxidation to cresols, which are vital for resins and disinfectants.
