一般描述

Pyridine is a high-purity polar, basic, and nitrogen-containing heterocyclic solvent widely used in analytical chemistry. Its high solvency power, miscibility with water and organic solvents, and compatibility with UV detection make it suitable for LC/MS, GC, and other chromatographic techniques, especially in the analysis of polar and basic compounds.

应用

Pyridine can be used as a:
  • Solvent for sample preparation and derivatization in GC analysis of polar compounds, including alcohols, esters, and organic acids.
  • Mobile phase component or sample diluent in LC-MS workflows, particularly for pharmaceutical, metabolomic, and environmental analyses due to its ionization efficiency and low background noise.

包装

M-Bottle for Solvents
As a global leader in lab reagents, we are constantly looking for new ways to optimize the safety of our products. The newly developed 4L solvent bottle design features advanced sealing technology that eliminates leaks to make the handling of solvents safer and more convenient than ever before.
