The present invention provides hapten derivatives useful for the preparation of antigens, antibodies and reagents for use in immunoassays for the detection of LSD and 2-oxo-3-hydroxy LSD. In the present invention, the 2-oxy LSD nucleus is derivatized out of the indole nitrogen to form an aminoalkyl derivative. The resulting haptens can then be further modified at this functionalized position for linking to appropriate immunogenic or labeling groups to provide reagents for immunoassays having substantially equal specificity for both LSD and 2-oxo-3-hydroxy-LSD.

The invention provides derivatives of efavirenz and methods of making derivatives of efavirenz. The derivatives include immunogenic compounds for producing antibodies to efavirenz and labeled efavirenz tracers. These compounds are useful in immunoassay methods for determining efavirenz.
A photolabel, a biotin tag, and a moenomycin ligand have been attached orthogonally to the three functional groups of isoserine to provide compound 13 that is to be used in affinity labeling of penicillin binding protein 1b. The urethane group in 13 can be cleaved with n-butylamine in methanol or water.
