U-48800 Online order

Description

U-48800 is a synthetic compound from the benzamide opioid class that was originally researched as part of pharmacological studies to develop new painkillers.
In recent years, this substance has gained increasing attention in scientific and forensic research, as it provides a model for studying the mode of action of strong opioid receptor agonists.
In contrast to traditional opioids such as morphine or fentanyl, U-48800 is used exclusively in controlled laboratory environments, where it serves as a reference substance for biochemical analyses.

Chemical structure and classification

Chemically, U-48800 belongs to the group of Benzamide opioids and is structurally closely related to the substances U-47700 and AH-7921.
The systematic chemical name is N-[2-(dimethylamino)cyclohexyl]-N,N-dimethylbenzamide.
The molecular structure contains a substituted benzamide core, which is extended by a cyclohexyl side chain with a dimethylamine residue.
This structural configuration gives the substance a pronounced lipophilicity and high receptor affinity, which makes it interesting for pharmacological studies.

Physical-chemical data

• Sum formula: C₁₇H₂₆N₂O
• Molecular weight: approx. 274.4 g/mol
• Appearance: white to beige crystalline powder
• Solubility: soluble in organic solvents (e.g. ethanol, chloroform)
• Stability: temperature-sensitive, store away from light and in a dry place

These chemical characteristics form the basis for the analytical characterization and understanding of the physical properties of U-48800 in scientific studies.

Pharmacological properties

U-48800 acts as Agonist at the µ-opioid receptor (MOR) and shows similar pharmacological activity to other benzamide opioids.
These receptors play a central role in pain regulation and are the main target of many analgesics.
In preclinical studies, U-48800 showed high receptor affinity and strong analgesic potency, making it a useful model in the study of opioid-mediated mechanisms.

Mechanism of action

After binding to the µ-receptor, U-48800 inhibits the activity of adenylate cyclase, reduces the influx of calcium ions and promotes the outflow of potassium ions.
These processes lead to the hyperpolarization of postsynaptic neurons, which reduces neuronal excitability and thus the perception of pain.
This mechanism is at the center of current research on opioid signal transduction pathways.

Research and scientific applications

In modern pharmacological research, U-48800 is used as a model substance for the investigation of Receptor binding, signal transmission and tolerance development used.
It also serves as a reference standard in forensic laboratories to identify synthetic opioids in biological samples.
Due to its stable chemical structure and defined purity, the substance is suitable for quantitative analyses and methodical validations.

Central research areas

• Receptor pharmacology: Investigation of the binding affinity to µ, δ and κ opioid receptors
• Toxicological studies: Determination of metabolic pathways and degradation products
• Forensic analytics: Development of new detection methods using LC-MS/MS
• Pharmacokinetics: Analysis of half-life and metabolization in in-vitro systems
• Comparative studies: Investigation of the structure-activity relationships within the U-opioid series

The combination of these research approaches makes it possible to better understand the pharmacological basis of synthetic opioids and to develop new strategies for safe analgesics.

Analytical identification

For the identification and quantification of U-48800, analytical laboratories mainly use Gas chromatography-mass spectrometry (GC-MS) and
Liquid chromatography coupled with tandemMass spectrometry (LC-MS/MS) used.
These methods enable reliable detection even in complex biological matrices such as blood, urine or tissue extracts.

In addition Infrared (IR) and Nuclear magnetic resonance spectroscopy (NMR) to confirm the molecular structure and purity.
The combination of these methods ensures precise chemical characterization and minimizes analytical uncertainties.

Toxicological aspects

U-48800 has a very high potency, which can cause clear physiological effects in experimental systems even at low concentrations.
For this reason, use is only permitted in professionally equipped laboratories under strict safety supervision.
In toxicological models, the effects on respiration, circulation and neuronal activity in particular are investigated.

U-48800 is metabolized by oxidative demethylation and hydroxylation, resulting in several inactive metabolites.
The identification of these degradation products is essential for forensic analyses and for the evaluation of toxic mechanisms of action.

Safety measures in the laboratory

As it is a highly active research chemical, proper handling of U-48800 is crucial.
All work should be carried out in accordance with the principles of Good Laboratory Practice (GLP) be carried out.
Exposure to the substance must be avoided at all costs.

Recommended safety precautions

• Wear a lab coat, safety goggles and chemical-resistant gloves
• Only work under a functioning chemical fume hood
• Use of closed sample containers
• Immediate disposal of contaminated materials in accordance with safety guidelines
• Keep an emergency shower and eyewash station available in the laboratory area

Compliance with these security measures protects the research staff and ensures the integrity of the experimental data.

Storage and stability

For long-term stability, U-48800 should be stored under optimal conditions.
We recommend a temperature of 2-8 °C, protection from direct sunlight and humidity and storage in tightly closed, labeled containers.
Under these conditions, the chemical integrity is maintained over longer periods of time.

Legal status

U-48800 is registered in most countries as a controlled substance classified.
In Germany, it falls under the Narcotics Act (BtMG), in the United States, it has been adopted by the Drug Enforcement Administration (DEA) classified as „Schedule I“.
In the European Union, Canada, Australia and Switzerland, possession, distribution or use outside authorized research facilities is also prohibited.

This regulation serves to protect against misuse and ensures that the substance is handled exclusively within a scientific framework.
Researchers require appropriate permits and safety certificates before they are allowed to use U-48800.

Research relevance and scientific significance

U-48800 offers researchers a valuable opportunity to study the mechanisms of opioid receptor activation and to better understand the pharmacological basis of pain perception, tolerance and dependence.
It plays a key role in the development of analytical methods that can precisely detect synthetic opioids.

In addition, research with U-48800 provides important data for the toxicological evaluation of new substances.
These findings help authorities and scientists to identify risks at an early stage and develop appropriate safety guidelines.

Conclusion

U-48800 is an important research substance within the benzamide opioid class.
Its strong receptor activity, chemical stability and defined structure make it a relevant substance in pharmacological and forensic research.
However, responsible, legally compliant handling is essential in order to avoid risks and gain scientific knowledge safely.

In basic research, U-48800 contributes to a better understanding of opioid-based signaling mechanisms and supports the further development of analytical methods.
It therefore remains a central model molecule for studies in the field of modern neuropharmacology and toxicology.
