Description

Description générale

Dichloromethane, also known as Methylene chloride, is commonly used as a solvent with a wide range of applications. Due to high solubility, it is used to perform nonlinear transmission (NLT) measurements. Additionally, it is used as an effective extraction solvent, allowing for the separation and purification of desired substances from mixtures.

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.
