  • Sodium Citrate Tribasic Dihydrate

    CAS NO: 6132-04-3

    Molecular Formula: C6H5O7•2H2O•3Na
    Molecular Weight: 294.1

    Alternate Names: Citric acid trisodium salt dihydrate; Trisodium citrate dihydrate
    Application: Sodium Citrate Tribasic Dihydrate (Molecular Biology Grade) is for the preparation of total ribosomal RNA from E. coli
    CAS Number 6132-04-3
    Purity: ≥99.5%
    Molecular Weight: 294.1
    Molecular Formula: C6H5O7•2H2O•3Na
    Description Sodium Citrate Tribasic Dihydrate (Molecular Biology Grade) is a source of Citric acid, a key metabolic intermediate. Citrate is the starting point of the tricarboxylic acid cycle. Its concentration also coordinates several other metabolic pathways. Citric acid can form complexes with various cations, particularly with iron and calcium. In animals, citric acid improves the utilization of nutritional calcium.
    Usage : Preparation Instructions:
    One gram of sodium citrate dissolves in 1.3 ml of water at 25 °C and in 0.6 ml of boiling water. Poorly soluble in alcohol.
    pH: 7.5 – 9.0 (0.1 M in H2O, 25°C)
    Storage/Stability:
    Citrate buffers (pH 3-5) exhibit excellent stability at room temperature. Dilute solutions of citric acid (non-sterile) may ferment if left at room temperature. Non-sterile solutions should be stable for months stored at 2-8 °C.
    Appearance : Powder
    Physical State : Solid
    Solubility : Soluble in water (29.4 g/L at 20 °C). Insoluble in alcohol.
    Storage : Store at room temperature
    Melting Point : >300° C (lit.)
    Boiling Point : 309.6° C at 760 mmHg
    Density : 1.86 g/cm3
