Product nameColorless Citric Acid Crystals as Blood Collection Tube Additives CAS77-92-9 PackagePlastic Bottle Minimum Order Quantity10g MW 192.122 Formula C6H8O7 Purity 99% Citric acid is an important organic acid, also known as citric acid, colorless crystal, often containing one molecule of water of crystallization, odorless, strong acidity, and soluble in water. Its calcium salt is easily dissolved in cold water than hot water, and this property is commonly used to identify and separate citric acid. Anhydrous citric acid can be obtained by controlling a suitable temperature during crystallization. It has many uses in industry, food industry, and cosmetics industry. Usage In the formation of prothrombin activator and subsequent coagulation, calcium ions must be involved. The citrate ion and the calcium ion can form a soluble complex which is difficult to dissociate, thereby lowering the calcium ion concentration in the blood and blocking the blood coagulation. This product is used as an in vitro anticoagulant when blood transfusion or laboratory blood sample anticoagulation. Citric Acid Crystals is mainly used as a sour agent, a solubilizer, a buffer, an antioxidant, a deodorant, a flavor enhancer, a gelling agent, a toner, and the like. In addition, citric acid also inhibits bacteria, protects color, improves flavor, and promotes sucrose conversion. Citric acid also has a chelation that removes certain harmful metals. Citric acid prevents oxidation caused by enzyme catalysis and metal catalysis, thereby preventing discoloration of quick-frozen fruit agprp gel preparation, potassium oxalate anticoagulant
