Product: Sodium Citrate (Trisodium Citrate Dihydrate, Na₃C₆H₅O₇·2H₂O)

CAS No.: 6132-04-3
Hazard Class: Non-hazardous
UN No.: Non-regulated
Appearance: White crystalline powder

Description: Sodium citrate is produced through neutralization of citric acid with sodium hydroxide, serving as a multifunctional food additive (E331iii) and buffering agent with excellent chelating properties. Its trisodium structure provides pH stabilization (effective range 3-7.5), emulsification in processed cheeses (1-3%), and anticoagulation in blood collection tubes (0.5M solution). The compound exhibits high water solubility (72g/100mL at 25°C) and forms stable complexes with calcium/magnesium ions (log K=3.5 for Ca²⁺), making it ideal for detergent builders and pharmaceutical alkalizers.
