vinculado a la estructura molecular de una sustancia o la información descriptiva por el Sistema de Registro de Sustancias (<i>Substance Registration System</i>) de la <a href="/wiki/Administraci%C3%B3n_de_Alimentos_y_Medicamentos" title="Administración de Alimentos y Medicamentos">Administración de Alimentos y Medicamentos</a> (FDA). Un UNII siempre tiene diez caracteres de longitud, y se genera al azar, para que no contenga ninguna información inherente sobre el tiempo de entrada o el tipo de sustancia. </p><p>El SRS es usado para generar identificadores permanentes y únicos para las sustancias en productos regulados, tales como ingredientes de <a href="/wiki/Medicamento" title="Medicamento">medicamentos</a>. El sistema utiliza la estructura molecular y la información descriptiva para definir una sustancia y generar un UNII. El principal medio para la definición de una sustancia es por su estructura molecular representada en un plano bidimensional. Cuando una estructura molecular no está disponible (por ejemplo, productos botánicos), el UNII se define a partir de la información descriptiva.<sup id="cite_ref-1" class="reference separada"><a href="#cite_note-1"><span class="corchete-llamada">[</span>1<span class="corchete-llamada">]</span></a></sup> </p><p>El procedimiento y manejo del SRS es proporcionado por el Consejo SRS, que incluye expertos de la FDA y el <a href="/wiki/Farmacopea_de_Estados_Unidos" title="Farmacopea de Estados Unidos">United States Pharmacopeia</a> (USP).<sup id="cite_ref-2" class="reference separada"><a href="#cite_note-2"><span class="corchete-llamada">[</span>2<span class="corchete-llamada">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Ejemplos">Ejemplos</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Identificador_de_ingrediente_%C3%BAnico&action=edit&section=1" title="Editar sección: Ejemplos"><span>editar</span></a><span class="mw-editsection-bracket">]</span></span></div> <table class="wikitable"> <tbody><tr> <th>Término preferido</th> <th>UNII </th></tr> <tr> <td><a href="/wiki/Testosterona" title="Testosterona">Testosterona</a></td> <td>3XMK78S47O </td></tr> <tr> <td><a href="/wiki/Metadona" title="Metadona">Metadona</a></td> <td>UC6VBE7V1Z </td></tr> <tr> <td><a href="/wiki/Agua" title="Agua">Agua</a></td> <td>059QF0KO0R </td></tr></tbody></table> <div class="mw-heading mw-heading2"><h2 id="Referencias">Referencias</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Identificador_de_ingrediente_%C3%BAnico&action=edit&section=2" title="Editar sección: Referencias"><span>editar</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="listaref" style="list-style-type: decimal;"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text">William A.
