2-Hydroxypropanoic acid(CAS: 26023-30-3)

2-Hydroxypropanoic acid, also known as lactic acid (CAS: 26023-30-3), is a colorless, syrupy liquid at room temperature. It has a molecular weight of approximately 90.08 g/mol. Lactic acid is slightly soluble in water and has a characteristic sour taste. It is a weak organic acid with a pKa of about 3.86. The compound is highly reactive and can form esters, salts, and participate in esterification reactions.

2-Hydroxypropanoic acid (lactic acid, CAS: 26023-30-3) can be synthesized through microbial fermentation, particularly from carbohydrates like sugars. Another common method involves the hydration of acetylene with water in the presence of a strong acid catalyst. The fermentation process yields high purity lactic acid with good selectivity and yield, while the hydration method is more suitable for large-scale production.

2-Hydroxypropanoic acid (lactic acid, CAS: 26023-30-3) is widely used in the food and beverage industry for flavoring and preservation. It is also important in the pharmaceutical industry for making drugs and intermediates. In the cosmetic industry, it serves as a moisturizer and exfoliant. Additionally, lactic acid is used in the production of fibers, plastics, and in biodegradable polymers for various applications.

When handling 2-Hydroxypropanoic acid (lactic acid, CAS: 26023-30-3), always wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Work in a well-ventilated area or in a fume hood. Ensure proper storage in a cool, dry place away from direct sunlight and heat sources. In case of a spill, neutralize the acid with a base, and dispose of the solution according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and safety information.
