Povidone Iodine (CAS 25655-41-8) is a chemical compound recognized globally for its broad-spectrum antimicrobial properties. Understanding its chemical characteristics and manufacturing process is crucial for R&D scientists, procurement managers, and formulators looking to source this vital ingredient. This article provides an in-depth look at Povidone Iodine from a chemical perspective, backed by insights from a leading manufacturer in China.

The molecular formula of Povidone Iodine is typically represented as (C6H9NO)n•xI2, where 'n' denotes the polymerization of vinylpyrrolidone and 'x' indicates the complexed iodine content. Its molecular weight is approximately 364.95 g/mol. A key characteristic is its appearance: a yellow-brown to red-brown crystalline powder, which is slightly odorous. This distinct color is indicative of the iodine complex.

Solubility is a critical parameter for formulation. Povidone Iodine is readily soluble in water, ethyl alcohol, isopropyl alcohol, polyethylene glycol, and glycerol. This high solubility in polar solvents makes it highly adaptable for various liquid formulations. Conversely, it is insoluble in non-polar solvents such as chloroform, carbon tetrachloride, hexane, and acetone. For manufacturers aiming to buy Povidone Iodine, understanding these solubility profiles is essential for product development.

Stability under normal temperatures and pressures is another significant advantage. This stability contributes to its long shelf life when stored correctly, typically in a cool, dry, well-ventilated area in tightly closed containers. The melting point is reported as 300°C (dec.), indicating its thermal robustness under typical processing conditions. These properties solidify its position as a reliable ingredient for long-term storage and application.

The manufacturing of Povidone Iodine involves the controlled complexation of elemental iodine with polyvinylpyrrolidone. Strict quality control measures are implemented throughout the production process to ensure the accurate percentage of available iodine (typically 9.0% to 12.0%), low levels of impurities, and adherence to international pharmacopeial standards.
