We provide this information to support responsible, lawful research. As a primary supplier, Davechemicals.com ensures researchers have access to meticulously verified, high-purity compounds like Flubromazolam powder.
🔬 What Is Flubromazolam (JYI-73)?
Flubromazolam is a synthetic benzodiazepine analogue, more specifically a triazolobenzodiazepine. This places it in the same structural family as pharmaceutical alprazolam and triazolam, but with significant modifications. The addition of a bromine atom and a fluorine atom to the core structure radically alters its pharmacokinetics, resulting in extreme potency and an extended duration of action.
According to authoritative chemical databases, its IUPAC name is 8-Bromo-6-(2-fluorophenyl)-1-methyl-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepine. It was first identified in the public domain around 2013-2014 as part of the wave of designer benzodiazepines appearing online. Its primary mechanism of action, like all classical benzodiazepines, is positive allosteric modulation of the GABA-A receptor in the central nervous system, leading to neuronal inhibition. However, its affinity and efficacy at these receptors are profoundly heightened.

📊 Flubromazolam vs. Common Benzodiazepines
To grasp the exceptional nature of Flubromazolam, one must compare it to familiar benchmarks. The table below illustrates its standing relative to other compounds. Data is synthesised from psychonaut community reports, analytical studies, and pharmacological literature.
Table 1: Benzodiazepine Potency & Duration Comparison
| Compound | Approximate Potency (vs. Diazepam) | Onset of Action | Primary Half-Life | Key Research Notes |
|---|---|---|---|---|
| Flubromazolam (JYI-73) | ~600x | Intermediate (30-60 min) | Extremely Long (12-24h+) | Notable for prolonged sedation & amnesia. High accumulation risk. |
| Diazepam (Valium) | 1x (Baseline) | Fast | Very Long (20-100h) | Standard reference compound. |
| Alprazolam (Xanax) | ~20x | Fast | Short-Intermediate (6-12h) | High potency but shorter duration. |
| Clonazolam | ~200-300x | Fast | Long (12-24h) | Known for high anxiolytic and sedative potency. |
| Etizolam | ~10x | Fast | Short (3-5h) | Thienodiazepine; similar effects but different structure. |
The data is unequivocal: Flubromazolam is in a league of its own regarding potency and half-life. This is why it has earned a reputation as a compound requiring the utmost respect in a research setting. For researchers studying metabolite formation or long-term receptor adaptation, its profile is uniquely significant.
⚠️ The Flubromazolam Profile: Documented Effects & Substantiated Risks
What does the available evidence say about Flubromazolam’s effects? Sourced from experience repositories and toxicology reports, its profile is consistent and severe.
Primary Reported Effects:
- Profound Sedation and Hypnosis: Its most dominant characteristic is intense, long-lasting sedation.
- Anterograde Amnesia: Pronounced memory impairment for events occurring after exposure is frequently reported.
- Muscle Relaxation and Ataxia: Significant impairment of motor coordination.
- Anxiolysis: Reduction of anxiety, though often overshadowed by sedation.
Substantiated Risks and Harms:
- Overdose Potential: Due to its µg-range activity, the margin between a standard research dose and a toxic one is perilously thin. Overdose presents as profound CNS depression.
- Prolonged Duration and Next-Day Impairment: Effects routinely last over 18 hours, with “hangover” effects like residual sedation and cognitive fog lasting days.
- Tolerance and Dependence: Rapid tolerance development is documented. Physical dependence can establish itself swiftly, leading to a severe withdrawal syndrome characterised by seizures, psychosis, and protracted anxiety.
- Behavioural Disinhibition: Paradoxical reactions like increased risk-taking or aggression, though less common, have been noted.
A case report published in the Journal of Analytical Toxicology has documented Flubromazolam involvement in impaired driving cases and fatalities, often in combination with other depressants. This underscores the compound’s real-world danger. For a deeper look at potent benzodiazepines, our analysis on highly potent designer benzodiazepines provides further context.

🧪 Handling Flubromazolam in the Laboratory: A Non-Negotiable Protocol
1. Preparation: Always use a calibrated, high-precision microgram balance (0.001mg sensitivity) in a clean, dedicated space. Wear appropriate PPE (lab coat, gloves, safety glasses).
2. Volumetric Dosing: Due to its potency, preparing a volumetric solution is the only safe method for accurate dilution. Dissolve a precisely weighed amount in a suitable solvent (e.g., high-grade propylene glycol or ethanol) to create a known concentration (e.g., mg/mL).
3. Secure Storage: Store the primary powder and any solutions in a locked, cool, and dry cabinet, clearly labelled with contents, concentration, date, and hazard warnings.
4. Waste Disposal: Contaminated materials and waste must be disposed of as hazardous chemical waste in compliance with local regulations.

❓ Frequently Asked Questions (FAQs) on Flubromazolam
What is the half-life of Flubromazolam?
The half-life of Flubromazolam is exceptionally long, estimated to range from 12 to 24 hours or more based on metabolite analysis. This leads to significant drug accumulation with repeated dosing, a key factor in its toxicity profile.
How does Flubromazolam compare to Clonazolam?
Both are ultra-potent designer benzodiazepines. Flubromazolam is generally reported to be more sedating and hypnotic with a longer duration, while Clonazolam (which you can learn more about in our guide on where to buy Clonazolam online) is often described as having more pronounced euphoric and anxiolytic effects, though still with a very long half-life.
Is Flubromazolam legal in the UK/US/Australia?
Legality is fluid. Flubromazolam is often controlled under analogue acts (like the UK’s Psychoactive Substances Act 2016) or specific blanket bans (US Federal Analogue Act, though enforcement varies). In Australia, it is typically scheduled as a controlled substance. Researchers must verify current statutes in their jurisdiction. We only supply to regions where possession for research is legally permitted.
What are the main metabolites of Flubromazolam?
Current forensic analysis, referenced in literature from the Cayman Chemical analytical catalogue, suggests metabolic pathways involve hydroxylation and debromination. The exact primary metabolites are still a subject of ongoing forensic research.
Can you buy Flubromazolam powder online safely?
The safety of buying Flubromazolam powder online hinges entirely on vendor legitimacy. Reputable suppliers like Davechemicals.com provide verifiable purity data, secure transactions, and discrete packaging for laboratory materials. Avoid any vendor that does not offer analytical proof of content.
