2-Hydroxypropanoic-2,3-^13C2 acid, also known as labeled lactic acid, is a stable isotope-labeled form of lactic acid, which is a naturally occurring organic acid. This compound features a hydroxyl group (-OH) and a carboxylic acid group (-COOH) attached to a three-carbon backbone, making it a member of the hydroxy acids. The presence of ^13C isotopes at the 2 and 3 positions allows for its use in various analytical applications, particularly in metabolic studies and tracer experiments. Lactic acid is known for its role in anaerobic metabolism and is produced in muscles during intense exercise. It is also utilized in food preservation, cosmetics, and as a chemical intermediate in various industrial processes. The labeled version can be particularly useful in research settings to trace metabolic pathways and understand the dynamics of carbon flow in biological systems. As with many organic acids, it is soluble in water and exhibits typical acid-base behavior.
