摘要
试制了3-氯-2-氟苯磺酰胺(CFBS)样品,用1 H NMR、13C-NMR、ESI-MS、HPLC对其分子结构、分子量和质量分数进行了确认,对该样品进行IR、XRD和熔点表征。结果表明,该样品确认为CFBS,质量分数≥99.8%,熔点范围为156.2~157.3℃。
3-Chloro-2-fluorobenzene sulfonamide(CFBS)was prepared and its molecular structure,molecular weight and mass fraction were confirmed by 1 H NMR,13 C NMR,ESI-MS and HPLC.In addition,the compound was characterized by IR,XRD and melting point instrument.The results show that the mass fraction is above 99.8%,its melting point is 156.2~157.3℃.
