Synthesis and Structure Characterization of ¹³C₁-DDT

Chlorobenzene and ¹³C-chloral were used as the raw materials to generate the target product ¹³C₁-DDT in concentrated sulfuric acid as catalyst.The isotope labeled compound was characterized by DSC, FT-IR, 1H NMR, ¹³C NMR and MS. The results showed that the chemical purity of the product was better than 99% and its isotopic abundance was more than 99%. The yield of product was 51%. ¹³C₁-DDT product could be used as standards.
