Product Description
3-Amino-2-oxazolidinone (AOZ) is the metabolite of furazolidinone. 3-Amino-2-oxazolidinone as an indicator for the detection of furazolidinone residues.
3-Amino-2-oxazolidinone (AOZ) is the major metabolite of the veterinary nitrofuran antibiotic furazolidone. Nitrofurans are synthetic antibacterial agents that have been banned for use in food-producing animals in many countries. AOZ is used as a marker residue to monitor the illegal use of furazolidone in food products.
Product Application
Overview
3-Amino-2-oxazolidinone (AOZ) is a small-molecule metabolite of furazolidinone, a nitrofuran-class antimicrobial. AOZ is widely recognized as a key marker for furazolidinone residues, making it an essential compound for studies in drug metabolism, food safety, and residue monitoring. Supplied at ≥98% purity, this research-grade compound provides laboratories with a reliable tool for investigating the metabolic fate of furazolidinone and developing detection assays.
AOZ possesses a heterocyclic oxazolidinone ring structure with an amino functional group, which contributes to its chemical stability and detectability in biological and food samples. Its well-characterized properties make it suitable for both analytical method development and mechanistic studies related to nitrofuran metabolism.

Research Applications
AOZ is primarily used in analytical and pharmacological research. Researchers use AOZ as an indicator to detect furazolidinone residues in food products, animal tissues, and biological samples. It can serve as a reference standard in chromatography, mass spectrometry, and other analytical assays to accurately quantify trace levels of furazolidinone metabolites.
Additionally, AOZ is valuable in pharmacokinetic and metabolism studies, where understanding the biotransformation of nitrofuran drugs is critical. Its inclusion in experimental protocols allows researchers to evaluate enzyme-mediated metabolism, clearance rates, and residue accumulation, providing important insights into safety and regulatory compliance.
This compound is strictly for research use only and is not intended for human or veterinary therapeutic applications. It provides a reproducible and high-purity standard to support residue detection, metabolism studies, and food safety research programs.

Biological Activity I Assay Protocols (From Reference)
Targets
3-Amino-2-oxazolidinone does not have a defined pharmacological target. It is a metabolite of furazolidone and serves as a biomarker for exposure to this banned antibiotic. Its detection in animal tissues indicates the prior administration of furazolidone.
ln Vitro
In vitro, 3-amino-2-oxazolidinone is used as an analytical standard for the detection of nitrofuran metabolites in food products. It does not exhibit significant biological activity itself. Its primary use is in the development and validation of analytical methods for food safety testing.
ln Vivo
In vivo, 3-amino-2-oxazolidinone is a metabolite that forms from the breakdown of furazolidone in animals. It can bind to tissue proteins, forming stable residues that persist for long periods. Its detection in edible tissues is a key indicator of illegal furazolidone use.
Enzyme Assay
In vitro assays for 3-amino-2-oxazolidinone typically involve its extraction from food or tissue samples and analysis by LC-MS/MS. The compound is derivatized with 2-nitrobenzaldehyde to form a more detectable derivative. It is used as a reference standard for method development and validation in food safety laboratories.
Cell Assay
For in vitro cell assays, 3-amino-2-oxazolidinone is not typically used as a treatment. It is used as a standard in analytical chemistry. Cell-based assays may be employed to study the toxicity or metabolic fate of nitrofurans, but AOZ itself is primarily a marker compound.
