In the realm of biochemical research and analytical chemistry, the precise quantification of amino acids and proteins is paramount. This is where o-Phthalaldehyde (OPA), a compound of formula C8H6O2, plays a critical role. As a leading manufacturer and supplier of fine chemicals in China, we understand the need for high-purity reagents like OPA to ensure reliable analytical outcomes.

Why is o-Phthalaldehyde Essential for Amino Acid Analysis?

o-Phthalaldehyde is renowned for its ability to react with primary amines in the presence of thiols, forming highly fluorescent isoindole derivatives. This reaction is particularly sensitive and specific, making OPA an ideal derivatizing agent for detecting and quantifying amino acids, peptides, and proteins through methods like high-performance liquid chromatography (HPLC) and capillary electrophoresis. Researchers often look to buy o-Phthalaldehyde to enhance the sensitivity and detection limits of their assays.

The process typically involves reacting the sample containing amino acids with OPA and a thiol (like mercaptoethanol or N-acetylcysteine) in a buffered solution. The resulting fluorescent compounds can then be easily detected using fluorometers. This technique is invaluable in various fields, including clinical diagnostics, food science, and fundamental biological research. For instance, understanding the amino acid profile of a protein is key to elucidating its structure and function.
