Molecule Structure Image



Trisodium citrate is the sodium salt of citric acid. It is chiefly used as a food additive, usually for flavor or as a preservative. As a conjugate base of a weak acid, it can perform as a buffering agent or acidity regulator, resisting changes in pH.Trisodium citrate is used to control acidity in some substances, such as gelatin desserts. It can be found in the mini milk containers used with coffee machines. It is used as an anticoagulant in blood transfusions. It is also used to relieve discomfort in urinary tract infections, such as cystitis, to reduce the acidosis seen in distal renal tubular acidosis, and can also be used as an osmotic laxative.
