Product Description
2-NP-AMOZ is a 2-nitrophenyl analogue of the antibiotic Furaltadone metabolite AMOZ and may be utilized to detect protein-bound AMOZ.
2-NP-AMOZ (CAS: 183193-59-1) is a 2-nitrophenyl derivative of AMOZ (3-amino-5-morpholinomethyl-2-oxazolidinone), which is the major metabolite of the nitrofuran antibiotic Furaltadone. Furaltadone is an antibiotic used in veterinary medicine, and its residues in food-producing animals are regulated. 2-NP-AMOZ is a derivatized standard used in analytical chemistry to detect protein-bound AMOZ residues in animal tissues.
Biological Activity I Assay Protocols (From Reference)
Targets
2-NP-AMOZ has no intrinsic pharmacological target. The parent drug, Furaltadone, is an antibiotic that targets bacterial cell wall synthesis. AMOZ is its stable metabolite. This analytical standard is not administered to animals; it is a chemical derivative used specifically for residue analysis. Its "target" is the detection of AMOZ in complex biological matrices for food safety testing.
ln Vitro
2-NP-AMOZ is not a pharmacologically active compound and is not used to measure in vitro activity. It is a derivatized standard for analytical chemistry. The parent compound, AMOZ, is a metabolite of the antibiotic Furaltadone. The purpose of this standard is not to assess activity but to enable precise detection of prohibited residues in animal tissues, such as chicken, pork, and fish.
ln Vivo
2-NP-AMOZ is an analytical standard and has no direct in vivo activity. It is used as a reference to monitor and quantify the presence of AMOZ residues in animal tissues for regulatory compliance and food safety. When an animal is treated with Furaltadone, the drug is rapidly metabolized to AMOZ, which binds to tissue proteins. This derivative is used to detect those bound residues.
Enzyme Assay
2-NP-AMOZ is used as a certified reference standard for non-cellular analytical method development. For LC-MS/MS analysis, the standard is dissolved in an organic solvent like methanol or acetonitrile to prepare a stock solution. This solution is then diluted to a series of known concentrations to create a calibration curve. It is also used as a quality control standard to verify the performance of the analytical instrument and the sample preparation method, ensuring accurate identification and quantification of AMOZ residues.
Cell Assay
2-NP-AMOZ is not used in conventional cell culture experiments. Its application is entirely analytical. To test the effectiveness of an analytical method, known as "spike-recovery," a known amount of the 2-NP-AMOZ standard is added (spiked) to a blank tissue sample homogenate (e.g., chicken liver) before the extraction and derivatization steps. The recovered amount is then measured, and the recovery rate is calculated to validate the accuracy of the method.
Animal Protocol
2-NP-AMOZ is not administered to animals for research purposes. However, it is a critical tool in studies involving animal safety and food production. For example, in a study where animals are treated with Furaltadone, tissue samples are collected. These samples are processed, and the 2-NP-AMOZ standard is used to quantify the amount of AMOZ residues. The concentration data obtained is used to determine the withdrawal period (the time required for drug residues to fall to safe levels) for the antibiotic.
ADME/Pharmacokinetics
2-NP-AMOZ is an analytical standard and has no pharmacokinetic parameters. The parent drug, Furaltadone, is rapidly metabolized to AMOZ in vivo, which binds to tissue proteins and has a long residence time in the body. The withdrawal period is set based on the depletion of these bound residues, which is measured using this analytical standard.
Toxicity/Toxicokinetics
2-NP-AMOZ is an analytical standard and is handled in very small quantities (micrograms to milligrams). The parent compound, AMOZ, is a metabolite of a carcinogenic antibiotic, and residues are regulated to be at very low (non-detectable) levels in food. As a research chemical, it is considered a potential health hazard and should be handled with strict precautions, including the use of disposable gloves, a chemical fume hood, and proper disposal procedures to avoid any exposure.

Additional Infomation
2-NP-AMOZ is not a drug but an analytical reference standard. Its sole purpose is to ensure the safety of the food supply. It is used by government regulatory agencies, food safety laboratories, and pharmaceutical companies to test for the illegal use of nitrofuran antibiotics (Furaltadone) in food-producing animals. This ensures that meat, milk, and other animal products are free from prohibited carcinogenic residues before they reach the consumer.
