Application

Dichloromethane can be used as a:
  • Solvent for the extraction of natural products and metabolites from biological samples, facilitating the analysis of compounds derived from biosynthetic pathways.
  • Mobile phase in high-performance liquid chromatography (HPLC) is used for the separation and characterization of biosynthetic compounds and their derivatives.
  • Recrystallization solvent for purifying active pharmaceutical ingredients (APIs) synthesized through biological methods, enhancing the quality and yield of the final product.

General description

Dichloromethane is a volatile solvent specifically formulated for use in high-performance liquid chromatography (HPLC) and various analytical applications. Its low viscosity and strong solvating ability make it an excellent choice for extracting and purifying organic compounds in biosynthesis processes.
