Product Overview
Acetonitrile, 99.8% pure and HPLC-grade, is a high-performance solvent designed for demanding analytical applications. Its ultra-low UV absorbance (≤190 nm) ensures minimal interference in spectrophotometric analyses, making it indispensable for high-sensitivity HPLC, LC-MS, and UV-Vis spectroscopy. The solvent’s exceptional polarity and miscibility with water and organic compounds enhance separation efficiency in chromatographic techniques. Manufactured under stringent quality controls, this acetonitrile undergoes rigorous purification to eliminate trace impurities, ensuring consistent baseline stability and peak resolution. Its low viscosity and high volatility facilitate rapid sample preparation and evaporation, reducing analysis time. The solvent is stabilized to prevent peroxide formation, extending shelf life without compromising purity. Packaged in amber glass bottles to prevent photodegradation, it maintains integrity during storage and transport. Compatible with most HPLC systems, this acetonitrile meets ACS, Reag. Ph Eur, and USP standards, guaranteeing reliability for critical laboratory workflows.
