Synthesis of Organothiophosphate Antigens for the Development of Specific Immunoassays

McAdam, David P.,Skerritt, John H.

, p. 959 - 967 (2007/10/02)

By use of t-butyl 3-propanoate (1), a general method was developed that allowed the preparation of analogues of specific organothiophosphates; these analogues are suitable for use as haptens in the development of tests for detection of the individual organophosphates.The bifunctional reagent (1) was conveniently prepared from readily available starting materials.
