CAS 77-92-9: Citric acid

Description: Citric acid, with the CAS number 77-92-9, is a weak organic acid that is naturally found in citrus fruits. It is a colorless, crystalline substance that is highly soluble in water, making it an effective acidulant in various food and beverage applications. Citric acid has a sour taste and is commonly used to enhance flavor, preserve food, and act as a pH stabilizer. Its molecular formula is C6H8O7, and it contains three carboxylic acid groups, which contribute to its acidity. In addition to its culinary uses, citric acid is utilized in pharmaceuticals, cosmetics, and cleaning products due to its chelating properties, which allow it to bind metal ions. It also plays a role in the Krebs cycle, a crucial metabolic pathway in living organisms. Citric acid is generally recognized as safe (GRAS) by regulatory agencies, making it a popular choice in various industries. Its biodegradable nature further enhances its appeal as an environmentally friendly option.
