n-Heptane

n-Heptane (C₇H₁₆) is a straight-chain aliphatic hydrocarbon with a boiling point of 98 °C, low polarity, and high volatility. It serves as a standard reference fuel for octane rating determination and as a nonpolar solvent in analytical chemistry and industrial cleaning. n-Heptane is also employed in the formulation of adhesives, coatings, and polymer processing. Due to its rapid evaporation rate and flammability, it should be handled in well-ventilated areas and stored in tightly closed containers away from ignition sources.

n-Heptane, Uvasol® pour la spectroscopie, Supelco®

Supplier: Merck

Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.
