Lactic acid solution
Lactic acid solution (CAS: 50-21-5), with the chemical formula CH3CH(OH)CO2H and a molecular weight of 90.08 g/mol, is a carboxylic acid commonly supplied as an ACS reagent. It is recognised for its chiral properties and utility in various chemical syntheses. This solution serves as a valuable building block in organic chemistry, particularly in asymmetric synthesis and the creation of complex organic molecules.
Chiral Synthesis
Lactic acid is a fundamental chiral building block used in the stereoselective synthesis of complex organic molecules and pharmaceutical intermediates. Its defined stereochemistry allows for precise control in creating enantiomerically pure compounds.
Organic Synthesis Reagent
As a versatile organic acid, it functions as a reagent and intermediate in numerous organic transformations. It is employed in the synthesis of esters, polymers, and other fine chemicals within research and industrial settings.
pH Adjustment and Buffering
In laboratory applications, lactic acid solution can be used for pH adjustment or as a component in buffer systems, though its primary use is as a synthetic precursor.
