Benzoic Acid CAS#65-85-0
Simple aromatic carboxylic acid with versatile synthetic applications.
Key precursor for producing phenol and caprolactam.
Widely used in manufacturing glycol benzoates.
Increasing use as a plasticizer in adhesive formulations.
Benzoic acid, the simplest aromatic carboxylic acid, is a weak acid that serves as a precursor for synthesizing numerous important organic compounds. Over 90% of commercial benzoic acid is directly converted into phenol and caprolactam. Its application in producing glycol benzoates, used as plasticizers in adhesive formulations, is also on the rise.

Benzoic acid is an important type of food preservative. Under acidic conditions, it inhibits molds, yeasts, and bacteria, although its effect on acid-producing bacteria is weaker. The optimal antimicrobial activity occurs at a pH range of 2.5 to 4, with an overall suitable pH range between 4.5 and 5.
