Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O.This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.
In the table above, it can be seen that water is the most polar-solvent, followed by DMSO, and then acetonitrile. Consider the following acid dissociation equilibrium: HA ⇌ A − + H + Water, being the most polar-solvent listed above, stabilizes the ionized species to a greater extent than does DMSO or Acetonitrile.
Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower.
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
Allergies to cats, a type of animal allergy, are one of the most common allergies experienced by humans.Among the eight known cat allergens, the most prominent allergen is secretoglobin Fel d 1, which is produced in the anal glands, salivary glands, and, mainly, in sebaceous glands of cats, and is ubiquitous in the United States, even in households without cats.
Domestic cat showing signs of aggression: Symptoms: Frantic scratching, biting or grooming of tail and lower back; aggression towards other animals, humans and itself; and a rippling or rolling of the dorsal lumbar skin. Usual onset: Around 9–12 months, or when the cat reaches maturity. Duration
All such derivatives feature O-bonded sulfoxides. The tricationic complex in [Rh(dmso) 6](O 3 SCF 3) 3 features one S-bonded and five O-bonded sulfoxide ligands. [10] The complex [Cu(Ph 2 SO) 4] 2+ is square planar, in contrast to the derivative with dmso ligands. The square planar d 8 complex [Rh(dmso) 4] + features a pairs of S- and O-bonded ...
Feline idiopathic cystitis begins as an acute non-obstructive episode and is self-limiting in about 85% of cases, resolving itself in a week. In approximately 15% of cases, it can escalate into an obstructive episode ("blocked cat") which can be life-threatening for a male cat. [5]
