Molecular formula: C7H5NaO2
Molecular Weight: 144.1032
Density: 1.44 g/cm³
Melting point: 300℃
Boiling point: 249.3°C at 760 mmHg

Description:
The chemical formula of sodium benzoate is C7H5NaO2, which is a white granule or crystalline powder, odorless or slightly benzoin odor, slightly sweet, astringent, with a relative molecular mass of 144.12, stable in the air, easily soluble in water, and its aqueous solution. The pH is 8 and it is soluble in ethanol.
Benzoic acid and its salts are broad-spectrum antimicrobial agents, but their antimicrobial effectiveness is dependent on the pH of the food. As the acidity of the medium increases, its bactericidal and bacteriostatic effects are enhanced, but in alkaline medium, the bactericidal and bacteriostatic effects are lost. The optimum pH value of its anticorrosion is 2.5~4.0.
Application：
1. Sodium benzoate is mainly used as a food preservative, and also used in the preparation of drugs, dyes, etc.
2. Sodium benzoate is used in the pharmaceutical industry and plant genetic research, as well as dye intermediates, fungicides and preservatives
3. Preservatives; Antimicrobials.
4. Sodium benzoate is also an important acid-type food preservative. Converts to the effective form benzoic acid on use. In addition, it can also be used as a preservative for feed.
5. Sodium benzoate is used as food additives (preservatives), fungicides in the pharmaceutical industry, mordants in the dye industry, plasticizers in the plastic industry, and as intermediates in organic synthesis such as spices.
6. Sodium benzoate is used as cosolvent in serum bilirubin test, food additive (preservative), bactericide in pharmaceutical industry, mordant in dye industry, plasticizer in plastic industry, and also used as an intermediate in organic synthesis such as spices body.
Sodium benzoate is a preservative. It is bacteriostatic and fungistatic under acidic conditions. It is used most prevalently in acidic foods such as salad dressings (vinegar), carbonated drinks (carbonic acid), jams and fruit juices (citric acid), pickles (vinegar), and condiments.
Sorbic acid, or 2,4-hexadienoic acid, is a natural organic compound used as a food preservative,Sorbic acid is a colourless solid that is slightly soluble in water and sublimes readily.
Methyl benzoate is an organic compound. It is an ester with the chemical formula C6H5CO2CH3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents.
