Toluene Extra Pure

Whatsapp Order

Toluene Extra Pure is a volatile, aromatic hydrocarbon widely used in analytical, organic, and industrial laboratory settings. As a high-purity, non-polar solvent, it is essential for reactions involving aromatic compounds, sample preparation, extraction, and cleaning. Toluene’s volatility and solvency make it indispensable in high-precision environments, though its flammability and health hazards require careful handling and strict safety compliance. Its Extra Pure grade ensures minimal impurities for research and sensitive formulation work.
