Product Technical Details

Product Overview

Potassium Bisulfate, also known scientifically as Potassium Hydrogen Sulfate, is a versatile inorganic compound widely utilized across various industrial and laboratory sectors. With the CAS number 7646-93-7, this chemical serves as a critical reagent in analytical chemistry and acts as a specialized additive in specific food processing applications. Our facility produces this compound under strict quality control measures to ensure consistency and reliability for downstream processes.

The compound is characterized by its white crystalline appearance and deliquescent nature. It exhibits high solubility in water, forming a solution that is highly acidic. This property makes it an essential component for pH adjustment, catalysis, and various synthesis routes where a strong acidic environment is required without introducing liquid acids. The molecular formula KHSO4 reflects its composition as an acid salt of sulfuric acid, providing a stable solid source of acidity.

Industrial Applications

The utility of Potassium Bisulfate extends across several key sectors due to its acidic properties and stability. In the laboratory environment, it is predominantly used as an analytical reagent for titrations and chemical testing. Its high purity grades ensure accurate results in sensitive measurements. In industrial settings, it functions effectively as a catalyst in organic synthesis reactions, facilitating processes that require precise acidification.

Additionally, specific grades are approved for use as food preservatives, helping to maintain product stability and safety in compliance with relevant regulatory standards. The chemical is also employed in metal treatment processes and wastewater management where pH control is critical. Our manufacturing process ensures that impurities such as heavy metals, chlorides, and nitrogen compounds are kept to minimal levels, safeguarding the integrity of your final products.

Quality Assurance and Handling

As a global manufacturer, we prioritize safety and quality in every batch produced. Each shipment is accompanied by a Certificate of Analysis (COA) verifying that the product meets the specified technical requirements. Our quality control team conducts rigorous testing on assay content, insoluble matter, and trace impurities to guarantee performance.

Regarding handling and storage, Potassium Bisulfate should be kept in a cool, dry, and well-ventilated area at room temperature. Due to its deliquescent nature and acidic solution properties, appropriate personal protective equipment (PPE) is recommended during handling to prevent irritation. The product is packaged in 25Kg woven bags lined with double-layer plastic bags to ensure protection against moisture and contamination during transit. We support global shipping logistics to deliver bulk quantities efficiently to our partners worldwide.
