Ergocristine is an ergopeptine and one of the ergot alkaloids. As of February 24, 2010 Ergocrisine has been federally scheduled. Because of the existing Controlled Substance Act regulatory controls on the LSD precursors lysergic acid, lysergic acid amide, ergotamine, and ergonovine, clandestine laboratory operators have sought uncontrolled sources of precursor material for the production of LSD. This has led to the illicit utilization of the precursor chemical ergocristine as a direct substitute for ergotamine and ergonovine for the illicit production of LSD. In fact, the largest clandestine LSD laboratory ever, William Leonard Pickard and Clyde Apperson, that was seized by the DEA utilized ergocristine as the LSD precursor. Recipes documenting procedures for utilizing ergocristine in LSD synthesis are easily found on the Internet. The DEA determined that ergocristine was readily available from commercial chemical suppliers. DEA had identified at least three suppliers of ergocristine, of which one distributor is located domestically; the other two are based in Germany and the Czech Republic.

2,3-dibromodisuccinic acid is used in organic synthesis, one of the main uses is to be used as a biological intermediate. 2,3-dibromodisuccinic acid is an important raw material for the synthesis of vitamin H.

2-Aminobenzaldehyde is a natural product found in Philadelphus coronarius, Robinia pseudoacacia, and other organisms with data available.

4-hydroxybenzoyl hydrazide can be used as an index for the determination of carbohydrates. The acid hydrolyzable side chain of tissue (liver) bound 4-hydroxybenzoyl hydrazide can be used as a marker to monitor its residue in chickens.
