Products Description of Sodium Dihydrogen CitrateCAS18996-35-5
Industrial-grade sodium dihydrogen citrate features purity of at least 99%, appears as a white crystalline powder, and has no odor. It decomposes at a melting point of 150°C and breaks down before reaching its boiling point. At 25°C, its vapor pressure is less than 0.001mmHg, and the relative density is 1.85 at 20°C. It dissolves easily in water, is slightly soluble in maleic-anhydride.html">material/ethanol.html">ethanol, and does not dissolve in ether or chloroform. The product remains stable under normal storage conditions and should not be used with strong oxidizing agents or strong bases.

Product Application of Sodium Dihydrogen CitrateCAS18996-35-5
Sodium dihydrogen citrate works as a buffering agent and sequestrant. It also serves as a reducing agent and stabilizer during the synthesis of Fe3O4 platinum core/shell particles. Additionally, it is applied in the electrochemical reduction of protons at carbon fiber electrodes with or without platinum nanoparticles. It also supports the characterization of carbon-based electrode materials used as cathodes in half-cell setups.
