一般描述
Dichloromethane (DCM) is a chlorinated organic solvent with a wide range of industrial applications. It has C2v symmetry, low boiling point, high density and is immiscible in water. Degradation of DCM by various methods has been reported. Ultrasonic absorption studies of liquid DCM shows strong relaxation effect. A study reports the dielectric characteristics of DCM over a wide frequency range. DCM is susceptible to degradation with time, which can be suppressed by adding amylene as a stabilizer.
应用
符合 ACS 规范。
Dichloromethane (Methylene chloride) may be used in the following processes:
- To compose ultrasonic baths for cleaning and protection of aluminum coating over atactic-PMMA (poly(methyl methacrylate)) for dielectric studies.
- Preparation of AMBF3 (ammoniomethyltrifluoroborate)-conjugated biomolecules.
- Sample preparation for GC-MS (Gas Chromatography-Mass Spectrometry) analysis.
- Preparation of ammonium acetate solvent mixture in combination with isopropanol, acetonitrile and water for mass spectral analysis of neutral lipids.
- Quantification of glutathione (GSH) and glutathione disulfide (GSSG) in biological samples by HPLC and spectrophotometry.
- As an extractant for 2,2-dithioethyl-4-(2′-pyridyl)-4-butyro-γ-lactone.
