Sodium Benzoate, also known as Sodiumato Benzoatato, Antimol, Ucephan, Benzoate of Soda, and Sobenate, has the chemical formula C7H5O2Na or C7H5NaO2 or C6H5COONa. It appears as colorless or white hygroscopic crystals or crystalline powder with no odor and astringent taste. It is freely soluble in Water and sparingly soluble in Alcohol at ambient conditions. On a lab scale, it is produced synthetically by the neutralization of Benzoic Acid with Sodium Bicarbonate, Sodium Carbonate or Sodium Hydroxide. Lab grade chemicals possess reasonable purity but do not comply with any official standard for quality or purity like the ACS Grade, the USP Grade, or the FCC Grade. The Lab Grade is also known as Laboratory Reagent (LR) and Chemically Pure (CP). Lab Alley’s Sodium Benzoate, Lab Grade is available for sale online at laballey.com. It is highly recommended for educational institutes and research labs.
