GC-DMS industrial dimethyl sulfate purity measurement gas chromatograph
Colorless to slightly brown oily liquid. There is an ethereal smell. Can be decomposed by strong alkali. It can dissolve 18g in 100ml water at 18℃ and hydrolyze rapidly. Soluble in ethanol, ether, dioxane, acetone and aromatic hydrocarbons, slightly soluble in carbon disulfide and aliphatic hydrocarbons. The relative density (d204) is 1.3322. Melting point -27°C. The boiling point is about 188°C (decomposition), 76°C (2.0kPa).
Dimethyl sulfate, an organic compound, a colorless or slightly yellow, oily flammable liquid with a slight onion smell. It is easily hydrolyzed into sulfuric acid and methanol at 50°C or alkaline water. Decomposes slowly in cold water. It is combustible when exposed to heat, open flame or oxidant. Dimethyl sulfate is a reagent that can methylate DNA. After methylation, DNA can be degraded at the methylated position.
There is no corresponding standard for the purity determination of industrial dimethyl sulfate. Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times and takes scientific development as the guide. Under the leadership of Manager Wang Xiaoying, relying on Xiangying Institute of Analytical Technology, Engineering Research Institute, Analysis and Testing Center, and 3 scientific research units have developed GC-DMS to create industrial dimethyl sulfate purity measurement gas chromatograph, equipped with special chromatographic columns, special sampling device (anti-virus device), this technology is currently Apply for protection. Haohan Chromatography provides detailed analysis solutions, and Haohan Chromatography masters core technologies.
