<h3>Overview</h3>
<p>Olanzapine Impurity 5 is a critical reference standard for pharmaceutical quality control, defined as N-[(4-methyl-1-piperazinyl)methyl]-2-methylthio-9H-pyrido[3,4-b]indole. Synthesized via alkylation of the pyridoindole core with methyl piperazine derivatives, it serves to validate purity profiles in antipsychotic formulations. <strong>Molecular Formula</strong>: C<sub>17</sub>H<sub>20</sub>N<sub>4</sub>S; <strong>CAS No.</strong>: 164866-63-9.</p>
<h3>Application</h3>
<ul>
<li><li>Quality Assurance: Used in HPLC/GC methods to identify and quantify trace impurities in Olanzapine APIs.</li>
<li>Method Validation: Essential for establishing specificity and accuracy limits during drug development.</li>
<li>Regulatory Compliance: Supports submission dossiers to FDA and EMA regarding impurity thresholds.</li>
</ul>
<h3>Precautions</h3>
<p>Store under inert atmosphere at -20°C away from light. Handle with appropriate PPE to avoid dermal absorption; inhalation may cause respiratory irritation. Not intended for clinical administration but requires strict containment during analytical procedures.</p>
