1-Aminohydantoin hydrochloride is a major metabolite of nitrofurantoin in animal tissues and can be used as a standard for the determination of residues of veterinary agents in meat, milk et.al. 1-Aminohydantoin hydrochloride covalently binds to tissue proteins and is released from the tissues under slightly acidic conditions and derivatized with 2-nitrobenzaldehyde to form nitrophenyl derivatives of AHD before detection.

D-Tyrosine is the D-isomer of tyrosine. D-Tyrosine negatively regulates melanin synthesis by inhibiting tyrosinase activity. D-Tyrosine inhibits biofilm formation and trigger the self-dispersal of biofilms without suppressing bacterial growth.

2-Methylbenzaldehyde is an endogenous metabolite.

D-Leucine is a more potent anti-seizure agent than L-leucine. D-leucine potently terminates seizures even after the onset of seizure activity. D-leucine, but not L-leucine, reduces long-term potentiation but had no effect on basal synaptic transmission in vitro.

1-Dodecanol is an endogenous metabolite.

Phenoxyacetic acid is an endogenous metabolite.

3-Indoleacetonitrile is an endogenous metabolite.

2,6-Dihydroxyacetophenone is an endogenous metabolite.

4,4-Dimethoxy-2-butanone is an endogenous metabolite.

L-Prolylglycine is an endogenous metabolite.

Chlorobutanol hemihydrate is a pharmaceutical preservative with sedative-hypnotic actions. Chlorobutanol hemihydrate is active against a wide variety of Gram-positive and Gram-negative bacteria, and several mold spores and fungi. Chlorobutanol hemihydrate is widely used in food and cosmetic industry.

Thalidomide 5-fluoride is Thalidomide-based cereblon ligand?that incorporates to the ligand for IRAK4 protein by a linker to form PROTAC IRAK4 degrader-1.

6-Chlorovanillin is identified in waste waters from bleached kraft pulp mills in Ontario and earlier also elsewhere>[1].

Monoethyl itaconate is a free radical can be used for polymerization.

NH2-PEG1-C1-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.

Spinacine is an endogenous metabolite.

1-Methylhistamine dihydrochloride is a histamine metabolite.

Tetrazine-Amine is a tetrazine linker that can be used to covalently label live cells through a cycloaddition.

4-Fluorophenoxyacetic acid (4FPA) induces parthenocarpy. 4-Fluorophenoxyacetic acid (4FPA) protects cereals from piercing-sucking insects and thereby increases rice yield in the field.

m-PEG7-thiol is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.

L-Azetidine-2-carboxylic acid is an endogenous metabolite.

Nitroxynil, anthelmintic agent, is active against parasites in both adult and immature stages. Nitroxynil is widely used for the research of infection of Fasciola hepatica.

N,N,O-Tridesmethylvenlafaxine is an endogenous metabolite.

4-Hydroxy-3,3-dimethylcyclohexanone is a key intermediate for the synthesis of hAChE inhibitor.

2-Benzylsuccinic acid (DL-Benzylsuccinic acid) is an potent inhibitor of carboxypeptidase A (CPA).

2-Piperidone is an endogenous metabolite.

4-Methyl-1-phenyl-2-pentanone is an endogenous metabolite.

Tropic acid (DL-Tropic acid) is a laboratory reagent used in the chemical synthesis of Atropine and Hyoscyamine.

2-Ethylpyrazine is an endogenous metabolite.

Fenamic acid is a chloride channel blocker.
