2-Hydroxypropanoic acid(CAS: 26100-51-6)

2-Hydroxypropanoic acid, also known as lactic acid, is a colorless, syrupy liquid with a molecular weight of approximately 90.08 g/mol. It has a pKa of around 3.86. It is sparingly soluble in water but more soluble in organic solvents. Chemically, it is known for its reactivity in forming esters, amides, and salts. It can also undergo fermentation and can act as a reducing agent.

2-Hydroxypropanoic acid, or lactic acid, can be synthesized through fermentation of carbohydrates by certain bacteria, such as Lactobacillus. It can also be prepared by hydration of acetylene or by the reaction of 2-hydroxyethyl chloride with sodium hydroxide. The use of biocatalysts can enhance the selectivity and yield of the product.

2-Hydroxypropanoic acid, or lactic acid, is widely used in the pharmaceutical industry for the production of drugs, in the food industry as a preservative, in the cosmetic industry as a moisturizer, and in the polymer industry for the synthesis of biodegradable polymers. It is also used in the production of sensors and in the textile industry for treating fabrics.

When handling 2-hydroxypropanoic acid, or lactic acid, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from heat and ignition sources. In case of spill, use appropriate containment and disposal methods as per the Material Safety Data Sheet (MSDS/SDS). Fume hoods should be used when handling the substance to prevent inhalation exposure.
