Polyvinylpyrrolidone LR 500gr

Polyvinylpyrrolidone LR 500gr

SKU : O-5287.0500

CAS : 9003-39-8

Formula : (C6H9NO)n

Grade : Laboratory Reagent

Applications:
- Biotechnology: Used as a blocking agent in blotting (Denhardt’s buffer) and to remove polyphenols during DNA purification.
- Chemical Synthesis: Acts as a stabilizing agent for metallic nanoparticles (e.g., silver nanospheres) and as a reducing agent.
- Pharmaceutical Research: Used in the study of amorphous solid dispersions to enhance the solubility of poorly water-soluble drugs.

Polyvinylpyrrolidone (PVP) LR (Laboratory Reagent) is a synthetic, water-soluble, and biocompatible polymer used widely in research and analytical applications. It is a non-ionic polymer prepared from the polymerization of N-vinylpyrrolidone, generally appearing as a white to light yellow, hygroscopic powder.

Key Aspects of PVP LR:

- Grade (LR): “LR” stands for Laboratory Reagent, indicating it is suitable for general laboratory analysis, chemical synthesis, and research purposes, but not necessarily pharmaceutical or human injectables unless otherwise specified.
- Solubility: It is highly soluble in water and various organic solvents, including alcohols (methanol, ethanol).
- Role in Research: It serves as a capping agent in nanoparticle synthesis, a stabilizing agent in colloidal systems, and a dispersing agent.
- Molecular Weight Grades: PVP is available in different grades, typically denoted by “K” values (e.g., K25, K30, K90) which correspond to different molecular weights and viscosities.
