AbstractAlkyl methanesulfonates are genotoxic impurities that should be limited to an intake of not more than 1.5 µg/day, as regulated by the International Council for Harmonization guideline M7. We herein report a trace analysis of methyl methanesulfonate (MMS), ethyl methanesulfonate (EMS), and isopropyl methanesulfonate (IPMS) in the delgocitinib drug substance using liquid–liquid extraction, with an ionic liquid as the sample-solving medium, and direct injection gas chromatography detected with a flame-ionization detector. The proposed method takes advantage of the fine solubility of ionic liquids toward the drug substance, the good extraction efficiency of alkyl methanesulfonates in liquid–liquid extraction using the Chem Elut cartridge with low-polar organic solvents, and the ability of alkyl methanesulfonates to concentrate in minimum amounts of organic solvent, resulting in excellent sensitivity and selectivity. Specifically, for the preparation of the sample solution, a mixture of 1-butyl-3-methylimidazolium chloride, water, and acetonitrile was used as the sample-solving media, extracted with diethyl ether, and the eluent was concentrated to 1 mL. The method showed good linearity, accuracy, and precision from 1 to 5 ppm, and the limits of detection of MMS, EMS, and IPMS were 0.1, 0.05, and 0.05 ppm, respectively.

Electrochemical Capacity

In this paper, a promising new high-capacity anode material for lithium-ion batteries based on a highly dispersed search is considered. The powder was obtained using pulsed electrochemical cathodic reduction in an electrolyte from an ionic liquid choline chloride-ethylene glycol on a titanium vibrocathode. The discharge capacity of the anode material was 817 (mA·h)/g, which is close to the theoretically specific electrochemical capacity of tin 924 (mA·h)/g. The powder of the researchers for the dispersion and morphology of tin crystals. The particle size distribution of the particles with an increased fraction ratio of less than 0.1 μm and SEM-photographs of grains with a rhombohedral particle shape are presented. For research, we turned to this anode material the applied methods of electrochemical analysis: cyclic voltammetry, galvanostatic cycling and impedance spectroscopy in the process of charge and discharge of the electrode. Consideration of changes in the characteristics of the electrode under study using circuits for impedance spectroscopy during the formation of the lithium-tin intermetallic compound, as well as a change in the ratio It is shown that when the charging capacity is reached, close to theoretical intercalation can go through two ways: through SEI and intermetallic compound.
