Sodium chloride

Sodium chloride (NaCl) is an inorganic crystalline compound consisting of sodium and chloride ions, notable for its high solubility in water and melting point of 801 °C. It is extensively used in laboratories for preparing isotonic solutions, buffer systems, and calibration standards. In industrial and biotechnological processes, sodium chloride functions as an electrolyte, stabilizer, and osmotic agent. It is chemically stable and nonflammable but should be stored in tightly sealed containers to prevent moisture absorption (caking).

Sodium chloride is a commonly used chemical which is found widely in nature. It is considered to be an essential nutrient. Excess amounts of sodium chloride can destroy electrolyte balance and cause death in most animals, including humans.
Sodium chloride is used in a wide variety of biochemical applications, including intravenous fluids (normal saline is 0.9% w/v in water), density gradients, a diluent to increase ionic strength in buffers or culture media and in salt-out procedures in the isolation of DNA. It has also been used in high concentrations for preservation of foods since bacteria cannot grow in high salt conditions. Sodium chloride is widely used in protein crystallization.
