Ethers do have nonbonding electron pairs on their oxygen atoms, 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds. Application In Synthesis of 111-90-0.

Background: The aim of the present study is to increase the solubility of dihydroartemisinin (DHA) using the self-emulsifying drug delivery system (SEDDS). Methods: We first conducted solubility test and ternary phase diagram, then, in order to optimize the formulation of the DHA self-emulsifying agent, the design mixture method was selected in the design expert software. Next, optimal prescription validation and preliminary formulation evaluation were conducted. By comparing the oil-water partition coefficient in vitro, the improvement of the in vivo osmotic absorption of DHA via self-emulsification was evaluated. Results: The optimal prescription ratio of oleic acid polyethylene glycol glyceride, polyoxyethylene hydrogenated castor oil, and diethylene glycol monoethyl ether in the DHA self-emulsifying preparation = 0.511:0.2:0.289 (weight/weight/w), with a drug-loading capacity of 26.3634 mg/g, solubility of 2.5448 mg/mL, and self-emulsification time of 230 s. The solubility self-emulsification was approx. 20.52 x higher in DHA than in the crude drug. The self-emulsification could improve DHA permeability and promoting in vivo DHA absorption. Conclusion: The DHA SEDDS could significantly improve DHA solubility and in vivo absorption.
Application In Synthesis of 111-90-0, Diethylene glycol monoethyl ether appears as a colorless, slightly viscous liquid with a mild pleasant odor. Flash point near 190°F. Used to make soaps, dyes, and other chemicals.
Diethylene glycol monoethyl ether is a primary alcohol that is ethanol substituted by a 2-ethoxyethoxy group at position 2. It has a role as a protic solvent. It is a diether, a primary alcohol and a hydroxypolyether. It derives from a diethylene glycol., 111-90-0.
