For analytical chemists, achieving precise and sensitive detection of amino acids is paramount. NINGBO INNO PHARMCHEM CO.,LTD. is pleased to offer guidance on utilizing 4-Chloro-7-nitrobenzofurazan (NBD-Cl, CAS: 10199-89-0) as a superior derivatizing reagent for chromatography analysis of amino acids. This powerful tool enhances the detection limits and chromatographic behavior of these fundamental building blocks of life.

Amino acids, by themselves, often lack sufficient chromophoric or fluorophoric properties for direct detection in high-performance liquid chromatography (HPLC). This is where derivatization becomes essential. NBD-Cl, a well-established organic intermediate, excels in this role. Upon reaction with the amino groups of amino acids, it forms stable, highly fluorescent adducts. This process significantly amplizes the signal, allowing for the detection of even trace amounts of amino acids, which is critical in fields ranging from clinical diagnostics to food science.

The protocol typically involves mixing the amino acid sample with NBD-Cl in a suitable buffer system. The reaction kinetics are generally favorable, yielding fluorescent products efficiently. The resulting NBD-labeled amino acids can then be separated using standard reversed-phase HPLC columns. The emitted fluorescence, with excitation and emission maxima typically around 464 nm and 512 nm respectively, provides a distinct and sensitive signal for quantification. This method is a prime example of effective chromatography analysis of amino acids.

NINGBO INNO PHARMCHEM CO.,LTD. supplies high-purity NBD-Cl to ensure the reliability and reproducibility of these analyses. Our commitment to quality means that researchers can confidently purchase NBD-Cl for their critical analytical work.

The benefits of using NBD-Cl extend beyond just increased sensitivity. The labeled amino acids often exhibit improved chromatographic separation, leading to cleaner chromatograms and more accurate peak integration. This is particularly important when analyzing complex mixtures containing numerous amino acids. Mastering amino acid analysis with NBD-Cl empowers chemists with a robust method for comprehensive sample profiling.
