For researchers and lab managers in the pharmaceutical, food, and biotechnology sectors, accurate amino acid profiling is paramount. The quest for sensitive and reliable analytical methods often leads to O-Phthalaldehyde (OPA), a chemical reagent celebrated for its ability to form highly fluorescent derivatives with primary amines. This makes it an indispensable tool for techniques like High-Performance Liquid Chromatography (HPLC) and capillary electrophoresis.

As a leading O-Phthalaldehyde supplier, we understand the critical need for purity and consistency in analytical reagents. Our OPA, with a typical purity of ≥99.0% by GC, is meticulously manufactured to ensure optimal performance in demanding applications. When you buy OPA from us, you are investing in precision and reproducibility for your amino acid analysis workflows.

The magic of OPA lies in its reaction with primary amines in the presence of a thiol, such as 2-mercaptoethanol. This condensation reaction generates highly fluorescent isoindole compounds. The resulting fluorescence, typically with excitation around 340 nm and emission peaking at 455 nm, allows for the detection of amino acids, peptides, and even proteins at incredibly low concentrations – down to the picomole range. This sensitivity is a game-changer for quantifying trace amounts of these vital biomolecules.

Many procurement specialists ask about the best way to integrate OPA into their existing analytical setup. As a versatile chemical intermediate, OPA can be purchased in various forms, including ready-to-use solutions or as a high-purity powder for in-house preparation. For those looking for competitive O-Phthalaldehyde price in China, partnering with a reputable manufacturer like us ensures both cost-effectiveness and uncompromising quality. We facilitate easy sourcing for your laboratory needs.

Beyond its analytical prowess, OPA is also recognized for its potent disinfectant properties. While this article focuses on its analytical applications, it's worth noting that the same chemical integrity that makes it a superior analytical reagent also contributes to its effectiveness in other domains. However, for those specifically seeking to enhance their biochemical analyses, sourcing high-grade OPA is the key. We are dedicated to supporting scientific advancement by providing reliable access to essential chemical tools.
