  2. Polyvinylpyrrolidone - Wikipedia

    en.wikipedia.org/wiki/Polyvinylpyrrolidone

    Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.

  3. Polyvinylpolypyrrolidone - Wikipedia

    en.wikipedia.org/wiki/Polyvinylpolypyrrolidone

    Polyvinylpolypyrrolidone (polyvinyl polypyrrolidone, PVPP, crospovidone, crospolividone, or E1202) is a highly cross-linked modification of polyvinylpyrrolidone (PVP). The cross-linked form of PVP is used as a disintegrant (see also excipients) in pharmaceutical tablets. [1]

  4. N-Vinylpyrrolidone - Wikipedia

    en.wikipedia.org/wiki/N-Vinylpyrrolidone

    It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2] It is the precursor to polyvinylpyrrolidone (PVP), an important synthetic material. The NVP monomer is commonly used as a reactive diluent in ultraviolet and electron-beam curable polymers applied as inks, coatings or adhesives. [2]

  5. Povidone-iodine - Wikipedia

    en.wikipedia.org/wiki/Povidone-iodine

    Povidone-iodine is a chemical complex of the polymer povidone (polyvinylpyrrolidone, PVP) and triiodide (I − 3). [24] It is synthesized by mixing the PVP polymer with iodine (I 2), allowing the two to react. [25] It is soluble in cold and mild-warm water, ethyl alcohol, isopropyl alcohol, polyethylene glycol, and glycerol.

  6. α-Pyrrolidinopentiophenone - Wikipedia

    en.wikipedia.org/wiki/Α-Pyrrolidinopentiophenone

    α-Pyrrolidinopentiophenone (α-PVP), also known as α-pyrrolidinovalerophenone, O-2387, β-keto-prolintane, prolintanone, [2] [3] or desmethylpyrovalerone, is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug and often consumed for recreational reasons.

  7. Gelclair - Wikipedia

    en.wikipedia.org/wiki/Gelclair

    Gelclair is a medicinal oral gel containing polyvinylpyrrolidone (PVP) and hyaluronic acid [1] that coats the surface of the mouth forming a thin protective film over painful oral lesions, such as those caused by radiotherapy or chemotherapy treatment for cancer.

  9. 2-Pyrrolidone - Wikipedia

    en.wikipedia.org/wiki/2-Pyrrolidone

    2-Pyrrolidone itself is used in inkjet cartridges. [5] A variety of pharmaceutical drugs are 2-pyrrolidone derivatives, including cotinine, doxapram, povidone, and ethosuximide, and the racetams. The chemical is an intermediate in the production of the polyvinylpyrrolidone precursor vinylpyrrolidone. [3]
