Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
In the realm of analytical chemistry, precise and sensitive detection methods are crucial for research and quality control. Phthalaldehyde (CAS 643-79-8), often abbreviated as OPA, is a widely recognized and highly effective reagent for the pre-column derivatization of amino acids. This process is fundamental to High-Performance Liquid Chromatography (HPLC) methods, enabling the fluorescent detection and accurate quantification of amino acids, peptides, and primary amines.
As a specialized manufacturer and supplier of fine chemicals, we understand the importance of reagent quality for analytical applications. Our Phthalaldehyde is produced with a high degree of purity, typically 98% min, ensuring consistent and reliable derivatization results. The reaction of Phthalaldehyde with amino acids in the presence of a thiol, such as 2-mercaptoethanol, forms highly fluorescent isoindole derivatives. These derivatives exhibit strong emission at specific wavelengths, allowing for very low detection limits, often in the picomolar range. This sensitivity is indispensable for analyzing biological samples, food products, and pharmaceutical formulations.
For laboratories and research institutions seeking to purchase Phthalaldehyde for their amino acid analysis needs, sourcing from a reputable supplier is vital. We offer Phthalaldehyde that is not only of high quality but also competitively priced, particularly for bulk orders. Our position as a manufacturer in China allows us to maintain a stable supply chain and provide cost-effective solutions to our global clientele. If you are looking to optimize your HPLC assays for amino acid profiling, protein hydrolysis analysis, or even histamine detection, consider our Phthalaldehyde.
