Abstract

The method comprises: synthesizing the hapten 2-methyl-3-phenyl benzyl succinic acid ester (for short: LBC) and the 2-methyl-3-phenylbenzene benzoic acid (for short: LBY); coupling the LBc with protein to prepare the artificial immunity antigen and immunity rabbit to the specificity polyclonal antibody of Bifenthrin; coupling the LBy with the protein to prepare the envelope antigen; using the synthesized envelope antigen and specificity antibody to establish the enzyme immunoassay EIA analysis method; the detection range of the Bifenthrin can reach 0.016mg / L, and the linear range of it is 0.01-50mg / kg.

Embodiment Construction

[0032] 1 Synthesis of Bifenthrin Artificial Hapten

[0033] Based on the fact that 2-methyl-3-phenylbenzyl alcohol is the main component in the molecular structure of bifenthrin, and can fully expose the structural features and contain carboxyl groups that can be coupled with proteins, 2-methyl- Using 3-phenylbenzyl alcohol, succinic anhydride and anhydrous pyridine as raw materials, the hapten 2-methyl-3-phenylbenzylsuccinate (LBc for short) was synthesized through a one-step reaction. In order to improve the detection sensitivity through heterologous reaction, the hapten 2-methyl-3- Phenylbenzoic acid (abbreviated as LBy). After purification, the products LBc and LBy were subjected to mass spectrometry (ESI) and H NMR spectroscopy ( 1 H-NMR) identification, and confirmed by comparison with similar known compound data.

[0034] The structure of the hapten is as follows:
