Description

Potassium Hydroxide USP Grade CAS: 1310-58-3 | M.F: KOH | MW: 56.11, Buy now for Reproducible and reliable results from ChemieR Inorganic Reagent. All ChemieR Products are exclusively distributed by Dawn Scientific Inc.

Potassium hydroxide USP is a potent, inorganic base that presents itself as a white, hygroscopic solid. Its chemical formula is KOH. On an industrial level, it is manufactured through the electrolysis of potassium chloride. When dissolved in water, it creates a powerful alkaline solution. Potassium Hydroxide, also known as Caustic Potash or Potash lye, is an inorganic compound that serves as a classic strong base. While it is odorless in its pure state, it can absorb carbon dioxide from the atmosphere, resulting in the creation of potassium carbonate and the release of heat. The USP Grade of Potassium Hydroxide is distinguished by its high quality and purity, meeting the rigorous standards of USP (United States Pharmacopeia). It is used in many industrial and lab applications.

ChemieR provides an extensive selection of high-purity salts, acids, base and high purity solvents, including alkali metals, alkaline earth compounds, perchlorates, heavy metals, rare earths, transition metals, silver and precious metals, and triflates. ChemieR specialize in inorganic chemicals, offering materials with low moisture content and minimal trace metals. ChemieR stands out with a diverse range of laboratory chemicals, from organic and inorganic reagents to solvents.

Application :

  • Potassium hydroxide USP is frequently used to neutralize acids and prepare potassium salts of reagents.
  • It can be employed in the production of certain pharmaceuticals and chemicals.
  • It is a powerful base, making it effective for cleaning and degreasing surfaces, equipment, and industrial machinery.
  • In the biodiesel industry, it is used as a catalyst in the transesterification process to convert triglycerides (fats and oils) into biodiesel.

Benefits :

  • Meet the toughest regulatory standards for quality and purity
  • Its strong alkaline nature makes it effective in neutralizing acids and adjusting pH levels in different applications
  • Versatile and stable product
  • The high solubility of KOH in water makes it easy to handle and incorporate into various solutions
