<h3>Overview</h3>
<p>UNA-C(Ac)-CE Phosphoramidite is a specialized <strong>modified nucleoside building block</strong> used in solid-phase oligonucleotide synthesis. The compound features a cyclohexyl-ethyl (CE) protecting group and an acetyl (Ac) moiety, with the molecular formula <strong>C26H40N5O7P</strong>. While specific CAS registration data requires verification against proprietary databases, it serves as a critical reagent for introducing unique steric or electronic properties into therapeutic sequences.</p>
<h3>Application</h3>
<ul>
<li><strong>Antisense Oligonucleotides</strong>: Synthesis of modified siRNA strands for enhanced nuclease resistance.</li>
<li><strong>Therapeutic DNA/RNA Aptamers</strong>: Construction of high-affinity ligands for targeted drug delivery systems.</li>
<li><strong>Diagnostic Probes</strong>: Manufacturing fluorescently labeled probes for real-time PCR and microarray analysis.</li>
</ul>
<h3>Precautions</h3>
<p>This phosphoramidite is moisture-sensitive and must be stored under <strong>inert atmosphere</strong> at temperatures below -20°C to prevent hydrolysis. Strict adherence to PPE protocols is required during handling due to potential sensitization risks associated with phosphorus-containing compounds.</p>
