This study aims to develop a bio\u2010based multifunctional thermal stabilizer and biological compound system. Adenine was reacted with anhydrous zinc acetate to synthesize the adenine\u2010zinc complex (Ade\u2010Zn), and its successful synthesis was confirmed using infrared spectroscopy, elemental analysis, and TGA. The thermal stability of Ade\u2010Zn was evaluated through oven\u2010aging tests, thermogravimetric analysis, conductivity measurements, and Congo red tests, demonstrating its superior performance. Results showed that Ade\u2010Zn extended the complete discoloration time of PVC at high temperatures to 2 h. Additionally, its thermal weight loss rate was significantly lower than that of commercial zinc stearate, with reductions of 3.84% and 1.75% in the first and second weight loss stages, respectively. Furthermore, UV absorption spectroscopy confirmed that Ade\u2010Zn inhibits the formation of conjugated double bonds during PVC thermal degradation. The composite system of Ade\u2010Zn and theophylline (Tph) was also investigated. It doubled the retention time of initial whiteness and enhanced HCl absorption capacity, antioxidant activity, and antibacterial performance to varying degrees. Transition state analysis confirmed that Ade\u2010Zn inhibits the thermal degradation of PVC and promotes alternative reactions with lower energy barriers, leading to more thermodynamically stable products.<\/jats:p>","DOI":"10.1002\/marc.202500487","type":"journal-article","created":{"date-parts":[[2025,8,18]],"date-time":"2025-08-18T03:37:04Z","timestamp":1755488224000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Synthesis of Multifunctional Heat Stabilizer Bio\u2010Based Ade\u2010Zn and Its Application in PVC"],"prefix":"10.1002","volume":"46","author":[{"given":"Nan","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory of Synthesis Biological Colloids Jiangnan University School of Chemical and Material Engineering  Wuxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1408-2417","authenticated-orcid":false,"given":"Pingping","family":"Jiang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Synthesis Biological Colloids Jiangnan University School of Chemical and Material Engineering  Wuxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pingbo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Synthesis Biological Colloids Jiangnan University School of Chemical and Material Engineering  Wuxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuqi","family":"Qi","sequence":"additional","affiliation":[{"name":"Key Laboratory of Synthesis Biological Colloids Jiangnan University School of Chemical and Material Engineering  Wuxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Synthesis Biological Colloids Jiangnan University School of Chemical and Material Engineering  Wuxi China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shijun","family":"Chen","sequence":"additional","affiliation":[{"name":"Research and Development Department Linqu Qili Catalyst Co.
