Application:	Metal-cation-induced shifts in thiolate redox and reduced sulfur speciation.: This study explores the redox behavior of thiolates affected by metal cations in acetonitrile, shedding light on sulfur speciation processes critical for developing catalytic and environmental remediation technologies (Seo et al., 2024 ). Rational design and investigation of nonlinear optical response properties of pyrrolopyrrole aza-BODIPY-based novel push-pull chromophores.: Focused on nonlinear optics, this research uses acetonitrile as a solvent to study the optical properties of newly designed chromophores, contributing to advances in optical materials science (Kothoori et al., 2024 ). Acetonitrile real gas phase behavior from quasi-ideal gas to nanodroplets: A microscopical view.: Providing a microscopic insight into the phase behavior of acetonitrile, this research enhances understanding of fluid dynamics at nanoscale levels, relevant for both academic studies and industrial applications (Martínez et al., 2024 ). Crystalline CdS/amorphous Cd(OH)2 Composite for Electrochemical CO2 Reduction to CO in a Wide Potential Window.: Highlighting the role of acetonitrile in electrochemical setups, this study develops new materials for efficient CO2 reduction, potentially impacting energy conversion strategies globally (Hua et al., 2024 ).
Features and Benefits:	ReagentPlus^® solvents have a guaranteed purity ≥98.5% and are ideal for experiments and applications that need fewer specifications. They are primarily defined by assay specifications and offer suitable quality for general lab use.
General description:	Acetonitrile (MeCN), an aliphatic nitrile, is a colorless liquid with a characteristic odor. MeCN has low viscosity, high elution strength and is highly miscible in water. It is widely used as a solvent and intermediate in organic syntheses and is transparent to UV-visible light, making it highly applicable in spectrophotometric and fluorimetric techniques. It also plays a major role as an extractant medium in liquid-liquid extraction, solid-phase extraction or microextraction.
