compounds. In addition to carbon atoms, the atoms constituting the ring also contain at least one heteroatom. The most common heteroatoms are nitrogen atoms, sulfur atoms, and oxygen atoms.This organic compound can be divided into two categories: aliphatic heterocycles and aromatic heterocycles. Heterocyclic compounds are ubiquitous in the structure of drug molecules.</div> <div class="new_arrivals relate_product"> <h2 class="title">Browse more categories</h2> <div class="items"> <a href="https://www.echemi.com/category/emollient-c2736.html">Emollient</a> <a href="https://www.echemi.com/category/inorganic-salts-c1215.html">Inorganic Salts</a> <a href="https://www.echemi.com/category/aldehydes-c1318.html">Aldehydes</a> <a href="https://www.echemi.com/category/condensing-agent-c1521.html">Condensing Agent</a> <a href="https://www.echemi.com/category/water-retention-agent-c2124.html">Water Retention Agent</a> <a href="https://www.echemi.com/category/sweeteners-c2126.html">Sweeteners</a> <a href="https://www.echemi.com/category/colorant-c2132.html">Colorant</a> <a href="https://www.echemi.com/category/flame-retardants-c2221.html">Flame Retardants</a> <a href="https://www.echemi.com/category/gel-forming-c2746.html">Gel Forming</a> <a href="https://www.echemi.com/category/biocide-algicide-c2801.html">Biocide & Algicide</a> </div> </div> </div> </div> </article> <!-- 底部区域共通 --> <section class="index_footer"> <div class="width_1050"> <p class="tip">Trade Alert - Delivering the latest product trends and industry news straight to your inbox. <br />(We`ll never share your email address with a third-party.)</p> <div class="input_box clearfix"> <input id="mailSubscribe" type="text" placeholder='Input your Email address' /> <div class="subscribe_btn" onclick="mailSubscribe()">Subscribe</div> </div> <div class="footer_box1"> <div class="footer_list"> <div class="title">About Us</div> <div class="li"> <a href="https://group.echemi.com" target="_blank">About ECHEMI Group</a> <a href="https://www.echemi.com/echemi.html" >About Echemi.com</a> <a href="https://www.echemi.com/marketing-kit.html" >Marketing Kit</a> <a href="https://www.echemi.com/sitemap.html" >Sitemap</a> <a href="https://www.echemi.com/partners.html" >Partners</a> <a href="https://www.echemi.com/cms/546980.html" >Chemical Knowledge</a> <a href="https://www.echemi.com/community.html" >Community</a> </div> </div> <div class="footer_list"> <div class="title">Buy on ECHEMI</div> <div class="li"> <a href="https://www.echemi.com/list/products-A.html" >Search Products List Alphabetically</a> <a href="https://www.echemi.com/list/buy-A.html" >Shop Chemical Products Alphabetically</a> <a href="https://www.echemi.com/list/suppliers-A.html" >Find Suppliers Alphabetically</a> <a href="https://www.echemi.com/list/casno-1.html" >Get Chemical Data Numerically</a> <a href="https://www.echemi.com/suppliers/china-CN.html" >Find Suppliers by Region</a> <a href="https://www.echemi.com/searchInquiry.html" >Request for Quotation</a> <a href="https://www.echemi.com/promotion-list.html" >Promotion</a> <a href="https://www.echemi.com/list/topProducts-A.html" >Top Products</a> </div> </div> <div class="footer_list"> <div class="title">Sell on ECHEMI</div> <div class="li"> <a href="https://www.echemi.com/vipApply.html" >Supplier Membership</a> <a href="https://i.echemi.com/help/echemi-premium-courses.html" >Training Center</a> <a href="https://www.echemi.com/success-stories.html">Success Stories</a> </div> </div> <div class="footer_list"> <div class="title">Customer Services</div> <div class="li"> <a href="https://i.echemi.com/help.html" >Learning Center</a> <a href="https://www.echemi.com/conditions.html" >Terms of Use</a> <a href="https://www.echemi.com/privacy.html" >Privacy Notice</a> <a href="https://i.echemi.com/help-cms/1434561.html" >Policies</a> <a href="https://i.echemi.com/help-cms/1434554.html" >Rules</a> <a href="https://i.echemi.com/help-cms/2054829.html" >Penalty Rules</a> <a href="mailto:service@echemi.com">Submit a Dispute</a> <a href="https://www.echemi.com/contactinfo.html" >Contact Us</a> </div> </div> </div> <div class="icon_box"> <span>Follow Us</span> <a rel="external nofollow" href="https://www.facebook.com/echemii/" target="_blank"> <i class="iconfont">&#xe602;</i> </a> <a rel="external nofollow" href="https://x.com/Echemiqd" target="_blank"> <i class="iconfont">&#xe86f;</i> </a> <a rel="external nofollow" href="http://www.linkedin.com/company/qingdao-echemi-technology-co-ltd" target="_blank"> <i class="iconfont">&#xe605;</i> </a> </div> <div class="footer_box2"><a href="https://www.echemi.com/cms/2080900.html">National-level Technology-based SME</a><br><a href="https://www.echemi.com/cms/1416504.html">China's Top 100 Industrial Digitalization Enterprises List</a> <br> The Drafting Unit of the "Specification for Operation and Management of Self-build Cross-border E-commerce Website" of the CCPIT</div> <p class="reference"><a href="http://beian.miit.gov.cn" style="color: #AAB7CC;" target="_blank" rel="nofollow">鲁ICP备16009155号-1</a> | Copyright@Qingdao ECHEMI Digital Technology Co., Ltd.</p> </div> </section> <style> /*首页特有RFQ侧边栏导航链接样式开始*/ .aside_box .aside_btn_special { width: 45px;
