摘　　要：建立了环氧化酶-2(COX-2)选择性抑制剂塞来昔布的化学结构确证方法。通过元素分析(EA)、X射线衍射(XRD)、热分析(TG-DSC)、红外光谱(IR)、质谱(MS)、核磁共振谱(NMR)对塞来昔布的元素组成和化学结构进行测定。综合多种谱学技术确证了塞来昔布的化学结构为4-[5-(4-甲基苯基)-3-(三氟甲基)-1H-吡唑-1-基]苯磺酰胺。该方法可有效解析塞来昔布的光谱特性并推断其结构,为该类药物的鉴定及质量控制提供可靠参考。The chemical structure confirmation method of celecoxib is established,a selective inhibitor of cyclooxygenase-2(COX-2)is established.The elemental composition and chemical structure of celecoxib are determined by elemental analysis(EA),X-ray diffraction(XRD),thermal analysis(TG-DSC),infrared spectroscopy(IR),mass spectrometry(MS)and nuclear magnetic resonance(NMR).The chemical structure of celecoxib is confirmed to be 4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazole-1-yl]benzenesulfonamide.This method can effectively analyze the spectral characteristics of celecoxib and infer its structure,so as to provide a reliable reference for the identification and quality control of celecoxib.
