Description

General description

Citric acid trisodium salt corresponds to a molecular weight of 258 Da. It has high sodium content and sieving coefficients.

Application

Citric acid trisodium salt has been used:

• as a component of mobile phase buffer in high performance liquid chromatography analysis of dorsal striatum homogenates(124)
• as an electrolyte for NiW co-deposition(125)
• as a component of saline-sodium citrate (SSC) buffer for wash steps in probe hybridization(126)

Biochem/physiol Actions

Citric acid trisodium salt as a 4% solution is used commercially as an anticoagulant during blood storage. It is used in continuous renal replacement therapy (CRRT) as an regional citrate anticoagulation (RCA) agent. Citric acid trisodium salt is used as an electrostatic stabilizer for the generation of iron (II, III) oxide hollow microspheres nanoparticle.
