IMP 243 is a symmetric di-HSG (histamine-succinyl-glycine) bivalent hapten containing a Tscg-Cys ligand and two HSG groups. IMP 243 can be radiolabeled with ^99mTc-pertechnetate. IMP 243 can be conjugated to other peptides to design bispecific antibodies (bsMAbs) for cancer research.

HSMO9 is a (+)-methamphetamine (METH)-like hapten that can be coupled to a carrier protein. HSMO9 can be used in vaccine development.

FXb is an immunizing and functionalized hapten and can be used for protein bioconjugates preparation.

Methylpyrroporphyrin XXI acid is a hapten that can be coupled with bovine serum albumin and keyhole limpet hemocyanin. Methylpyrroporphyrin XXI acid can target porphyrin with IC₅₀ of 1.3 μM.

DOTA-Tyr-Lys-DOTA is a DOTA-based small molecule hapten. DOTA-Tyr-Lys-DOTAexhibits rapid clearance and low whole-body retention. DOTA-Tyr-Lys-DOTA can used in study pretargeted radioimmunotherapy.

DNP-PEG2-NHCO-C2-DBCO is a clickable hapten that bears a dinitrophenyl (DNP) moiety as the antibody‐recruiting motif at one end, a polyethylene glycol chain as a spacer and a dibenzocyclooctene at the other end for the SPAAC chemistry.

Dinotefuran-NHCO-propionic acid (4) is an antigen. Dinotefuran-NHCO-propionic acid can couple BSA and OVA to obtain the immunogen and the coating antigen (hapten-OVA conjugate) .

Dicamba-6-amino-6-oxohexanoic acid (DCh) is an immunizing and heterologous hapten, activated before removing the 1-tert-butyl-benzoate moiety.

Dicamba-5-aminopentanoic acid (DCc) is an immunizing and heterologous hapten, designed using the carboxylic acid group of dicamba to introduce a spacer arm for a better exposure of the herbicide's structure.

Cyromazine-3-mercaptopropanoic acid (Compound 7) is a hapten conjugated to BSA and OVA for immunoassays of triazine herbicides.

Clothianidin-2-S-propanoic acid is a clothianidin hapten. Clothianidin-2-S-propanoic can be used for the research of insecticide.

Cholic acid-cysteine-cyanuric chloride complex is a hapten linker molecule comprising of the antigen, cholic acid and the reactive group for covalent attachment, cyanuric chloride.

AMOZ-CHPh-4-O-acid is a hapten, containing 2 carbon and 1 oxygen spacer. AMOZ-CHPh-4-O-acid can be used for antibody production. AMOZ-CHPh-4-O-acid is coupled to BSA for immunogens and coupled to OVA for coating antigens.

AMOZ-CHPh-3-acid is hapten against furaltadone metabolite AMOZ. AMOZ-CHPh-3-acid can couple to BSA for immunogens and couple to OVA for coating antigen.

AMOZ-CH-acid (Hapten 5) is an immunizing and heterologous hapten. AMOZ-CH-acid and ovalbumin conjugate is a coating antigen that improves assay sensitivity.

Zeph is a small chemical group double heterologous hapten of Zep and combines with a specific antibody but lacks antigenicity of its own.

Ursodeoxycholic acid 7-N-acetylglucosaminide is an immunizing and heterologous hapten.

Trimethoprim fumaric acid (Compound CDI) is a universal hapten for ASGs (Antibacterial synergists) and can be used to design broadly specific monoclonal antibodies (mAbs) against ASGs. The mAb developed by Trimethoprim fumaric acid can be applied in ELISA to detect the residues of ASGs in foods of animal origin.
