Metonitazene for sale (Metonitazene (CAS 14680-51-4) – What is Metonitazene ?

Buy metonitazene online (CAS 14680‑51‑4) is a powerful synthetic opioid that has emerged in the research chemical market, often sold as a research chemical for laboratory use only. At Davechemicals.com, we supply high‑purity Metonitazene powder for forensic and analytical purposes, not for human or veterinary consumption. This article explains what Metonitazene is, its chemical profile, effects, risks, and why it’s strictly for research use only.

🔬 What is Metonitazene? (CAS 14680‑51‑4)

Metonitazene is a synthetic opioid belonging to the benzimidazole class, structurally related to other potent opioids like etonitazene and isotonitazene. It acts as a full agonist at the μ‑opioid receptor, producing strong analgesic and depressant effects similar to fentanyl and other high‑potency opioids.

Its chemical name is 2‑(1‑(2‑methoxyethyl)‑1H‑benzimidazol‑2‑yl)‑1‑phenylethan‑1‑one, and it is identified by the CAS number 14680‑51‑4. On the research chemical market, it is typically sold as a white to off‑white crystalline powder, intended for in‑vitro studies and forensic analysis.

Metonitazene is not approved for medical use anywhere in the world and is classified as a controlled substance or analogue in many countries, including the UK, USA, Germany, and Australia. It is strictly for laboratory research, not for human consumption.

🧪 Chemical Profile & Structure

Metonitazene is part of the “nitazene” family of synthetic opioids, which are known for their extreme potency and high risk of overdose. Its structure features a benzimidazole core with a phenylketone side chain and a methoxyethyl substituent, contributing to its strong binding affinity at opioid receptors.

Key identifiers:

Synonyms : Metonitazene
CAS: 14680-51-4
IUPAC 2-[2-(4-methoxybenzyl)-5-nitro-1H-benzimidazol-1-yl]-N,N-diethylethanamine
Molecular Formula : C21H26N4O3
Density : 1.2±0.1 g/cm3
Molecular weight: 382.464 g·mol−1
Appearance: White to off‑white crystalline powder
Purity ≥ 98%

Metonitazene is often compared to other nitazenes such as etonitazene, isotonitazene, and protonitazene, all of which are extremely potent and associated with a high risk of respiratory depression and fatal overdose.

💊 How Metonitazene Works in the Body

Metonitazene exerts its effects primarily by activating the μ‑opioid receptor in the central nervous system. This leads to:

• Strong analgesia (pain relief)
• Sedation and euphoria
• Respiratory depression
• Reduced heart rate and blood pressure
• Nausea, vomiting, and constipation

Because of its high potency, even microgram quantities can produce profound opioid effects. This makes accurate dosing extremely difficult and increases the risk of accidental overdose, especially when used outside a controlled laboratory setting.

Like other synthetic opioids, Metonitazene can cause physical dependence, tolerance, and severe withdrawal symptoms with repeated use. It also carries a high risk of addiction and life‑threatening respiratory depression, particularly when combined with other depressants like alcohol, benzodiazepines, or other opioids.

⚠️ Risks & Dangers of Metonitazene

Metonitazene is not a recreational drug and should never be used outside a professional research environment. The main risks include:

• Extreme potency: Much stronger than morphine or even fentanyl, making overdose very easy.
• Respiratory depression: Can cause shallow breathing, apnoea, and death, especially at higher doses or when mixed with other CNS depressants.
• Addiction and dependence: Rapid development of tolerance and physical dependence with repeated exposure.
• Withdrawal syndrome: Severe opioid withdrawal symptoms, including anxiety, muscle pain, insomnia, sweating, and gastrointestinal distress.
• Legal status: Classified as a controlled substance or analogue in many jurisdictions, including the UK, USA, Germany, and Australia. Possession, sale, or use may carry serious criminal penalties.

Because of these dangers, Metonitazene is strictly for forensic and research use only and must never be ingested, inhaled, or injected by humans or animals.

🌍 Legal Status & Regulations

Metonitazene is not approved for medical use and is tightly regulated in most countries:

• United Kingdom: Likely controlled under the Misuse of Drugs Act 1971 as a Class A drug or as a controlled drug analogue.
• United States: Treated as a Schedule I controlled substance analogue under the Federal Analogue Act, making possession and distribution illegal.
• Germany: Controlled under the Narcotics Act (BtMG) as a synthetic opioid.
• Australia: Regulated under the Poisons Standard and controlled as a Schedule 8 (S8) substance.

These laws mean that Metonitazene cannot be legally sold or used for human consumption. At Davechemicals.com, we only supply it as a research chemical for licensed laboratories, forensic services, and academic institutions.

• Work in a well‑ventilated area or fume hood to avoid inhalation.
• Avoid skin contact and never eat, drink, or smoke in the lab.
• Store in a cool, dry place, away from light and moisture, in a locked cabinet.
• Keep out of reach of unauthorised personnel, children, and animals.

In case of accidental exposure, follow standard laboratory safety procedures and seek medical attention immediately.
