2-NP-AHD, a 2-nitrophenyl derivative of AHD, is a metabolite of nitrofurans, a class of antibiotics, and serves as an indicator for the detection of illicit use of nitrofuran drugs.

1-Aminohydantoin hydrochloride is a significant metabolite of furantoin in animal tissues. It binds covalently to tissue proteins, is released under slightly acidic conditions, and can be detected by derivatization with 2-nitrobenzaldehyde forming a nitrophenyl derivative of AHD. It is used in assays to determine veterinary drug residues in meat and milk.

1-Amino Hydantoin-13C3 is the 13C and deuterated compound of 1-Amino Hydantoin. 1-Amino Hydantoin has a CAS number of 6301-02-6. 1-Aminohydantoin is a major metabolite of furantoin in animal tissues. 1-Aminohydantoin is covalently bound to tissue proteins, released from tissues under slightly acidic conditions, and can be detected by derivatization with 2-nitrobenzaldehyde to form a nitrophenyl derivative of AHD. 1-Aminohydantoin can be used as an assay for the determination of veterinary drug residues in meat and milk.
