CAS 50-21-5: Lactic acid

Description:Lactic acid, with the CAS number 50-21-5, is an organic acid characterized by its molecular formula C3H6O3. It is a colorless, syrupy liquid that is soluble in water, ethanol, and ether, making it versatile in various applications. Lactic acid exists in two stereoisomeric forms: L-lactic acid and D-lactic acid, with the L-form being the most prevalent in biological systems. It is produced naturally in the body during anaerobic respiration, particularly in muscle cells during intense exercise, and is also a byproduct of fermentation processes in certain bacteria. Lactic acid has a sour taste and is commonly used as a food preservative, flavoring agent, and acidulant in various food products. Additionally, it plays a significant role in the cosmetic and pharmaceutical industries due to its moisturizing properties and its ability to promote skin exfoliation. In industrial applications, lactic acid is utilized in the production of biodegradable plastics, solvents, and as a pH regulator in various formulations. Its biodegradable nature makes it an environmentally friendly alternative in many applications.
