As a supplier of Potassium Dihydrogen Phosphate, I often encounter questions from customers regarding its CAS number and other related details. In this blog post, I will delve into the significance of the CAS number for Potassium Dihydrogen Phosphate, its properties, applications, and why it is crucial for businesses to source this compound from a reliable supplier. <a href=\"https:\/\/www.zpjinxing.com\/water-treatment-agent\/potassium-dihydrogen-phosphate\/\">Potassium Dihydrogen Phosphate<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.zpjinxing.com\/uploads\/47183\/small\/liquid-polyferric-chloride0805c.jpg\"><\/p>\n<h3>What is a CAS Number?<\/h3>\n<p>The Chemical Abstracts Service (CAS) number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. It serves as a universal reference number that allows scientists, researchers, and industry professionals to accurately identify and communicate about specific chemical compounds. Each CAS number is a non &#8211; proprietary identifier, which means it can be used freely by anyone to refer to a particular chemical.<\/p>\n<p>The CAS number for Potassium Dihydrogen Phosphate is 7778 &#8211; 77 &#8211; 0. This number is recognized globally and is used in chemical databases, safety data sheets (SDS), regulatory filings, and scientific research to precisely identify this compound. When you see the CAS number 7778 &#8211; 77 &#8211; 0, you can be certain that it refers to Potassium Dihydrogen Phosphate, regardless of the brand or trade name under which it is sold.<\/p>\n<h3>Properties of Potassium Dihydrogen Phosphate<\/h3>\n<p>Potassium Dihydrogen Phosphate has several important properties that make it a valuable compound in various applications.<\/p>\n<ul>\n<li><strong>Chemical Formula<\/strong>: The chemical formula of Potassium Dihydrogen Phosphate is KH\u2082PO\u2084. It consists of one potassium ion (K\u207a), two hydrogen ions (H\u207a), one phosphate ion (PO\u2084\u00b3\u207b).<\/li>\n<li><strong>Physical Appearance<\/strong>: It is a white, odorless, crystalline powder. The crystals are typically small and have a granular texture.<\/li>\n<li><strong>Solubility<\/strong>: Potassium Dihydrogen Phosphate is highly soluble in water. This property makes it easy to use in aqueous solutions, which is advantageous in many applications such as fertilizers and food additives.<\/li>\n<li><strong>pH<\/strong>: An aqueous solution of Potassium Dihydrogen Phosphate is acidic, with a pH of around 4.4 &#8211; 4.7. This acidic nature can be utilized in various chemical processes and formulations.<\/li>\n<li><strong>Stability<\/strong>: It is relatively stable under normal conditions of temperature and pressure. However, like many chemical compounds, it should be stored in a cool, dry place away from incompatible substances.<\/li>\n<\/ul>\n<h3>Applications of Potassium Dihydrogen Phosphate<\/h3>\n<p>Potassium Dihydrogen Phosphate has a wide range of applications in different industries:<\/p>\n<h4>Agriculture<\/h4>\n<ul>\n<li><strong>Fertilizer<\/strong>: It is a popular fertilizer because it provides both potassium and phosphorus, two essential nutrients for plant growth. Potassium is important for overall plant health, disease resistance, and fruit quality, while phosphorus is crucial for root development, flowering, and seed production.<\/li>\n<li><strong>Foliar Spray<\/strong>: Potassium Dihydrogen Phosphate can be used as a foliar spray, which allows plants to absorb nutrients directly through their leaves. This method is particularly useful for correcting nutrient deficiencies quickly.<\/li>\n<\/ul>\n<h4>Food Industry<\/h4>\n<ul>\n<li><strong>Food Additive<\/strong>: It is used as a food additive, mainly as an acidity regulator, emulsifier, and stabilizer. In the food industry, it helps to control the pH of food products, improve texture, and prevent spoilage. For example, it can be found in dairy products, baked goods, and beverages.<\/li>\n<\/ul>\n<h4>Pharmaceutical Industry<\/h4>\n<ul>\n<li><strong>Buffer Solution<\/strong>: Potassium Dihydrogen Phosphate is used to prepare buffer solutions in pharmaceutical formulations. Buffer solutions help to maintain a stable pH, which is important for the stability and effectiveness of many drugs.<\/li>\n<\/ul>\n<h4>Chemical Industry<\/h4>\n<ul>\n<li><strong>pH Adjustment<\/strong>: It is used in various chemical processes to adjust the pH of solutions. Its acidic properties make it suitable for neutralizing alkaline substances or creating acidic environments for specific reactions.<\/li>\n<\/ul>\n<h3>Why Source Potassium Dihydrogen Phosphate from a Reliable Supplier?<\/h3>\n<p>As a supplier of Potassium Dihydrogen Phosphate, I understand the importance of providing high &#8211; quality products to our customers.
