General description

3-Nitrophenylhydrazine (3-NPH) is a derivatizing reagent used for the derivatization of carboxyl- and carbonyl-containing metabolites. This compound is also used as a high-efficiency chemical isotope-labeling reagent. Additionally, 3-nitrophenylhydrazine undergoes a condensation reaction with substituted benzaldehydes resulting in the formation of a series of ten substituted (E)-1-benzylidene-2-(3-nitrophenyl) hydrazine compounds.

Application

<ul>
<li><strong>Derivatization agent in analytical chemistry:</strong> 3-Nitrophenylhydrazine hydrochloride is employed as a derivatization agent for the determination of gamma-Hydroxybutyric acid in biological samples infected with Herpes Simplex Virus-Type 1, utilizing LC-MRM-MS techniques, providing enhanced detection capabilities in forensic and clinical toxicology (Osinaga et al., 2022).</li>
<li><strong>Residual analysis in pharmaceutical formulations:</strong> This compound is also used for the quantitative analysis of residual 4-nitrobenzaldehyde in chloramphenicol and its pharmaceutical formulations, employing HPLC with UV/Vis detection after derivatization with 3-nitrophenylhydrazine, offering a reliable method for ensuring the purity and safety of pharmaceutical products (Luo et al., 2018).</li>
<li><strong>Forensic application in decomposition analysis:</strong> Used to derivatized the blood samples collected at the time of forensic autopsy (Matoba et al., 2022).</li>
</ul>
