Usage

General Description

1-Butyl-4-methylpyridinium bromide is a quaternary ammonium compound with the chemical formula C$_{11}$H$_{16}$BrN. It is often used as a phase transfer catalyst and as an ionic liquid. 1-BUTYL-4-METHYLPYRIDINIUM BROMIDE is known for its colorlessness, its high solubility in water and organic solvents, and its hydroscopic nature. It generally comes in the form of a white or slightly yellowish powder. Because of its potential to cause harm to the eyes, skin, respiratory system and other organs upon contact, safety measures must be taken while handling it. The compound is predominantly used in the field of chemistry, specifically in chemical synthesis, pharmaceuticals, and electrochemistry.

Structural analysis of mono-substituted N-butyl-pyridinium salts: in search of ionic liquids

Four mono-substituted N-butylpyridinium salts, 1-butyl-4-dimethylaminopyridinium chloride [b4dmapy]Cl, 1-butyl-4-methylpyridinium bromide [b4mpy]Br, 1-butyl-4-methylpyridinium hexafluorophosphate [b4mpy][PF6], and 1-butyl-3-methylpyridinium hexafluorophosphate [b3mpy][PF6] were synthesized and characterized using single crystal X-ray diffraction. The crystal structures were examined with the intent of identifying ion interactions leading to higher melting points of the halide salts with respect to the [PF6]– salts. The changes in hydrogen bonding, C–H???π, and van der Waals interactions have been analyzed with respect to anion, functional groups, and the symmetry of the cation to establish interdependence with the compound’s physicochemical properties. It has been observed that the cation–anion interactions are represented by highly directional hydrogen bonds and show strong preference to positions of interaction depending on the anion. The cations of the halide salts show strong tendency towards higher dimensional formations, while those of the [PF6]– salts prefer low dimensional assemblies both being based mainly on the weaker van der Waals interactions. These interactions depend on the shape of the cation but may offer certain structure-ordering rigidity accommodating variable anions.

Correlation between lipophilicity of newly synthesized ionic liquids and selected: Fusarium genus growth rate

The purpose of the present study was to examine the effectiveness of 23 different synthesized ionic liquids (ILs) on Fusarium culmorum and Fusarium oxysporum growth rate. The strategy of IL synthesis was a structural modification of ionic liquids through changing the polarity of imidazolium and pycolinium cations and replacing halide anions with well known antifungal anions (cinnamate, caffeate and mandelate). The findings clearly suggest that the type of alkyl chain on the cation is the most determining factor for IL toxicity. In order to examine how IL structure affects their toxicity towards Fusarium genus, lipophilic descriptor AlogP is calculated from density functional theory and correlated with Fusarium growth rate. All these results demonstrate the high level of the interdependency of lipophilicity and toxicity for investigated ILs towards the Fusarium genus. The data collected in this research suggest that the inhibitory influence of ILs is more pronounced in the case of F. oxysporum.
