General description

4-hydroxyphenylpyruvic acid can be determined in pork meat and Iberian ham samples by a sensitive method of multiple reaction monitoring (MRM) by mass spectrometry.

Application

<ul>
<li><strong>Identification of serum biomarkers of ischemic stroke:</strong>4-Hydroxyphenylpyruvic acid is used as a potential diagnostic biomarker in the study to distinguish hypertensive ischemic stroke (IS) patients from both healthy individuals and those with hypertension (Zhao et al., 2023).</li>
</ul>

Preparation Note

50 gm of 4-Hydroxyphenylpyruvic acid dissolves in 1 mL of ethanol to yield a clear, light yellow solution.
