DL-Lactic Acid, with the CAS number 598-82-3, is a fascinating organic compound that serves as a cornerstone in numerous chemical applications. Chemically known as 2-Hydroxypropanoic Acid, it is a racemic mixture of D-Lactic Acid and L-Lactic Acid. Understanding its chemical structure, properties, and synthesis methods is crucial for B2B buyers looking to effectively utilize this versatile ingredient. If you are looking to buy this compound, insights into its chemistry can guide your selection.

The molecular formula of DL-Lactic Acid is C3H6O3, and its molecular weight is approximately 90.08 g/mol. Structurally, it features a carboxyl group (-COOH) and a hydroxyl group (-OH) attached to the same carbon atom, making it an alpha-hydroxy acid. This dual functionality is key to its reactivity and wide range of applications. It typically appears as a white crystalline powder with a melting point around 18°C, although its solutions can be liquid. Its properties, such as mild acidity (pKa at 25°C is 3.86) and solubility in water and methanol, make it amenable to various chemical processes.

The synthesis of DL-Lactic Acid commonly involves chemical methods. While L-Lactic Acid is primarily produced via fermentation using specific bacterial strains, DL-Lactic Acid is often synthesized through chemical routes. One such method involves the hydration of pyruvic acid or the hydrolysis of lactonitrile. These chemical synthesis pathways allow for the production of a racemic mixture, making it a cost-effective option for many industrial applications where stereospecificity is not critical. For manufacturers, these chemical processes ensure consistent quality and scalability.

The versatility of DL-Lactic Acid stems from its ability to act as a precursor for esters, salts, and polymers. As mentioned previously, it is a vital monomer for producing polylactic acid (PLA), a biodegradable polymer used in packaging, textiles, and biomedical applications. Furthermore, its derivatives, such as various lactate salts, are employed in food, pharmaceuticals, and personal care products. Understanding these chemical transformations is vital for formulators and chemists who plan to purchase it for downstream synthesis.
