<h3>Overview</h3>
<p>ISO-dG refers to isotopically labeled deoxyguanosine, a critical standard for metabolic tracing and mass spectrometry calibration. The core process involves enzymatic synthesis or chemical modification to ensure high isotopic purity. Molecular formula: <strong>C10H13N5O4</strong>; CAS No.: <strong>67-98-9</strong>.</p>
<h3>Application</h3>
<ul>
<li><strong>DNA Synthesis Analysis:</strong> Used as an internal standard in LC-MS/MS quantification.</li>
<li><strong>Metabolic Flux Studies:</strong> Traces nucleotide biosynthesis pathways in cell cultures.</li>
<li><strong>Quality Control:</strong> Validates analytical instruments in pharmaceutical R&D labs.</li>
</ul>
<h3>Precautions</h3>
<p>Store at -20°C under inert atmosphere to prevent hydrolysis. Handle with nitrile gloves; avoid direct skin contact. Not intended for clinical administration but strictly for laboratory research use only.</p>
