General description

Dichloromethane is a chlorinated hydrocarbon widely used in various analytical techniques, including High-Performance Liquid Chromatography (HPLC), Liquid Chromatography-Mass Spectrometry (LC/MS), and Gas Chromatography (GC). Its unique properties make it suitable for a range of applications in both research and industrial settings.

Application

Dichloromethane is used as a solvent:
  • To prepare spectroscopic samples.
  • For the dilution of s-diphenylaminostilbene which is used as a reference material for two-photon excited fluorescence (2PEF) measurement.

Packaging

is packaged in 4L polycoated glass bottle
M-Bottle for Solvents
