Salicylic Acid, identified by the CAS number 69-72-7, is a fascinating organic compound with a rich history and significant industrial applications. Its chemical name, 2-Hydroxybenzoic Acid, hints at its structure: a benzene ring with a hydroxyl group and a carboxyl group attached to adjacent carbon atoms. This specific arrangement imbues it with its characteristic properties, making it a valuable chemical intermediate and active ingredient.

The primary method for synthesizing Salicylic Acid on an industrial scale is the Kolbe-Schmitt reaction. This process involves heating sodium phenoxide with carbon dioxide under pressure. The resulting sodium salicylate is then acidified, typically with sulfuric acid, to yield pure Salicylic Acid. This synthesis pathway is critical for producing the compound efficiently and in the large volumes required by various industries.

Understanding the quality standards is paramount when sourcing Salicylic Acid. For pharmaceutical applications, adherence to pharmacopoeial monographs such as USP (United States Pharmacopeia), BP (British Pharmacopoeia), and EP (European Pharmacopoeia) is essential. These standards often specify a minimum purity of 99.5% and set limits for impurities. For cosmetic and industrial grades, while requirements may vary, consistency and purity remain key factors.
