Application:
Sodium Citrate Dihydrate (CAS: 6132-04-3), a conjugate base of a weak acid, can perform as a biological buffering agent because it resists changes in pH. Citric acid is one of a series of compounds responsible for the physiological oxidation of fats, carbohydrates and proteins to carbon dioxide and water. Sodium Citrate Dihydrate is often used to prepare sodium citrate buffer for antigen retrieval of tissue samples. The citrate solution is designed to break protein cross-links; thus, unmasking antigens and epitopes in formalin-fixed and paraffin embedded tissue sections, resulting in enhancing staining intensity of antibodies. Citrate has anticoagulant activity and as a calcium chelator, it forms complexes that disrupt the tendency of blood to clot. An anticoagulant also used as a biological buffer. Sodium Citrate Dihydrate is used as flavors, stabilizing agent, buffering agent, chelating agent, nutritional supplement of buttermilk, emulsifying agent and flavoring agent in food and beverage industry; Sodium Citrate Dihydrate has pH adjusting capability as well as having a good stability, and therefore can be used in the food industry. It has the greatest demand when being used as a food additive; As food additives, it is mainly used as flavoring agents, buffers, emulsifiers, bulking agents, stabilizers and preservatives. It can be used as anti-blood clotting,apophlegmatisant and diuretics in phamaceutical industry; it can replace sodium tripolyphosphate as a non-toxic detergent additives in detergent industry; it can also be used in brewing, injection, photography drugs and electroplating etc..
