  Dimethylsulfoxide (abbreviated as DMSO) is a sulfur-containing organic compound, with the English name Dimethylsulfoxide and the molecular formula (CH3)2SO. At room temperature, it is a colorless, odorless, transparent liquid with hygroscopicity and is flammable. It has the characteristics of high polarity, high boiling point, non-protonic, and miscibility in water. It has extremely low toxicity and good thermal stability. It does not mix with alkanes and is soluble in most organic substances such as water, ethanol, propanol, ether, benzene and chloroform. It is hailed as the "universal solvent". It is the one with the strongest dissolving power among the commonly used organic solvents. It can dissolve most organic substances, including carbohydrates, polymers, peptides, as well as many inorganic salts and gases. It can dissolve solute equivalent to 50-60% of its own weight (other common solvents can only dissolve 10-20%), so it is very important in sample management and h...

  Resorcinol Product Introduction Resorcinol (CAS 108-46-3 ) is an important organic chemical raw material belonging to the catechol family of compounds.
