Description

Propyl propionate (CAS No. 106-36-5) is a high-purity ester with the molecular formula C₆H₁₂O₂, widely used in industrial and research applications. This clear, colorless liquid exhibits a fruity odor, making it valuable as a flavoring agent and fragrance component. With a boiling point of approximately 122-124°C and a density of 0.881 g/cm³ at 20°C, it is miscible with most organic solvents but only slightly soluble in water. Our Propyl propionate is rigorously tested to ensure ≥98% purity (GC), making it ideal for synthetic chemistry, solvent formulations, and analytical applications. Packaged in amber glass bottles or chemical-resistant containers to ensure stability and longevity.
