Potassium pyrosulfate, identified by CAS number 7790-62-7, is an inorganic salt with a unique chemical structure and properties that make it valuable in several industrial applications. As a professional manufacturer and supplier of fine chemicals, we are pleased to offer high-quality potassium pyrosulfate and provide insights into its characteristics and procurement. This article details the key chemical properties of potassium pyrosulfate and offers a guide for businesses looking to buy this compound.

The chemical name for potassium pyrosulfate is dipotassium (sulfonatooxy)sulfonate, reflecting its structure which features two potassium cations and the pyrosulfate anion ([S2O7]2-). Its molecular formula is K2O7S2, and it has a molecular weight of approximately 254.32 g/mol. In its pure form, potassium pyrosulfate is typically a white crystalline powder or fused solid. A key characteristic is its solubility in water, where it hydrolyzes to form potassium bisulfate. This acidic nature is central to its primary applications.

One of its most significant uses is as an acid solvent in chemical analysis. When fused with samples, it creates a highly acidic medium capable of dissolving materials that are resistant to other acids. This makes it indispensable for preparing samples for quantitative analysis, ensuring complete dissolution and accurate measurements. For this purpose, a high purity, often with a minimum assay of 98%, is crucial. Any impurities could interfere with sensitive analytical techniques.

Another important application is in the steel industry, where it acts as an inclusion agent for electrolytic metal in steel analysis. This process aids in characterizing the non-metallic inclusions present in steel, which is vital for quality control and material development. The consistency and purity of the potassium pyrosulfate directly impact the reliability of these analyses.

For professionals looking to purchase potassium pyrosulfate, understanding the market dynamics is beneficial. China has a strong manufacturing base for inorganic chemicals, offering competitive pricing and a wide range of suppliers. When selecting a supplier, it is essential to prioritize manufacturers who adhere to international quality standards, such as GMP, SGS, USP, BP, EP, and FCC. These certifications ensure that the product meets stringent purity and performance requirements.

When initiating a purchase, consider requesting detailed quotations that include pricing, minimum order quantities (MOQ), and packaging options like 25kg bags. Many suppliers offer online purchase support, which can streamline the inquiry and ordering process. Engaging directly with a manufacturer can often lead to better pricing and a more secure supply chain. Always ensure the supplier can provide comprehensive technical documentation, including Safety Data Sheets (SDS) and Technical Data Sheets (TDS).

In conclusion, potassium pyrosulfate is a valuable inorganic chemical with significant applications in analytical chemistry and the steel industry. By understanding its chemical properties and following a guided approach to purchasing from reputable China manufacturers, businesses can secure a high-quality and cost-effective supply of this essential compound.
