WebDichloromethane (DCM) is a useful and advantageous solvent used in pharmaceutical development due to its low cost, miscibility with other organic solvents, high volatility, and ability to solubilize drug molecules of variable polarities and functionalities. Despite this favourable behaviour, efforts to ident WebReplace dichloromethane with comparable or better results • Eliminate the interference caused by the chemical stabilizers required for dichloromethane • Published reports demonstrate that a 3:1 blend of ethyl acetate and ethanol is a suitable replacement for dichloromethane without compromising chromatographic separation1 Typical Applications WebQuestion: Chloromethane can be thought of as resulting from methane via the replacement of one Hydrogen atom with a Chlorine atom. Subsequent replacements of H with Cl yield dichloromethane (CH2Cl2), trichlormethane (CHCl3) and tetrachlormethane (CCl4). Which of these three previous molecules will have all bond angles equal to each other? income tax file online india
