<h3>Overview</h3>
<p><strong>19-norandrostenedione</strong> is a synthetic androgenic steroid intermediate with the molecular formula C<sub>19</sub>H<sub>26</sub>O<sub>2</sub> (CAS No. 853-23-8). It is primarily manufactured via chemical synthesis from plant sterols or semi-synthetic routes involving dehydrogenation and structural modification.</p>
<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical Intermediates:</strong> Used as a key precursor for synthesizing anabolic steroids like nandrolone derivatives.</li>
<li><strong>Research Chemicals:</strong> Employed in metabolic studies to investigate androgen receptor pathways.</li>
<li><strong>Veterinary Medicine:</strong> Utilized in specific formulations for livestock growth promotion under strict regulations.</li>
</ul>
<h3>Precautions</h3>
<p>Strictly controlled as a precursor; unauthorized clinical use is prohibited. Store in a cool, dry place away from oxidizers. Handle with appropriate PPE due to potential endocrine disruption risks.</p>
