Overview
Benzyl benzoate (CAS 120-51-4) is an aromatic ester compound with excellent solvent properties and established antimicrobial activity. This colorless, oily liquid represents one of the most versatile benzyl esters in industrial chemistry, combining the structural elements of benzyl alcohol and benzoic acid. With its molecular formula C14H12O2 and molar mass of 212.24 g/mol, benzyl benzoate exhibits distinctive physicochemical properties that make it valuable across multiple technical applications. The compound demonstrates good thermal stability and moderate polarity, enabling its use as both a solvent and active ingredient in various formulations. From a safety perspective, benzyl benzoate is classified under the GHS system with pictograms GHS07 and GHS09, carrying the warning signal word due to its Acute Tox. 4 classification and Aquatic Chronic 2 environmental hazard rating. As an ADR Class 9 substance, it requires appropriate handling protocols during transport and storage. While generally considered less hazardous than many industrial solvents, proper ventilation and personal protective equipment remain essential during handling operations. The compound finds primary industrial applications as a plasticizer in polymer formulations, where it enhances flexibility and workability of various plastic materials. Additionally, its solvent properties make it valuable in specialty chemical synthesis and extraction processes. Unlike more complex quaternary ammonium compounds such as benzyl(tributyl)azanium;4-hydroxynaphthalene-1-sulfonate, benzyl benzoate offers simpler handling characteristics while maintaining effective performance in targeted applications. OYSI maintains reliable European supply chains for benzyl benzoate, ensuring consistent availability for technical and industrial customers across various sectors.
