Chemical Name: 1,3-Dimethylbutylamine
Common Names: DMBA, 2-Amino-4-methylpentane
Chemical Formula: C6H15N
CAS Number: 108-18-9
Physical State: Usually found as a clear, colorless to pale yellow liquid, sometimes sold as a powder in supplement markets.
Odor: Sharp, fishy, ammonia-like smell.
Uses: Sometimes included in pre-workout dietary supplements or studied as a stimulant, not approved for food or pharmaceutical use in most countries.
Main Health Concerns: Exposure to 1,3-Dimethylbutylamine can irritate the skin, eyes, and respiratory tract. Overexposure might cause symptoms such as headache, nausea, increased heart rate, and in higher doses, potential cardiovascular issues. Oral ingestion or inhalation carries higher risks, especially for individuals with pre-existing heart conditions.
Physical Hazards: Highly flammable liquid and vapor. May form explosive mixtures with air. Can cause burns on contact with open wounds or mucous membranes.
Environmental Hazards: Not known to be highly toxic to aquatic environments, but as with most organic amines, caution in release is warranted.
Main Component: 1,3-Dimethylbutylamine (purity ranges from 95% to 100% in most samples found in chemical markets).
Common Impurities: Trace amounts of other amines, methylated hydrocarbons, and sometimes solvent residues if not properly purified.
Inhalation: Move affected person to fresh air. Encourage deep, calm breathing. If problems persist, seek immediate medical attention.
Skin Contact: Remove contaminated clothing. Wash affected area thoroughly with soap and water. Avoid rubbing the substance into the skin.
Eye Contact: Rinse cautiously with plenty of water for several minutes. Remove contact lenses if present. Seek prompt medical attention if irritation remains.
Ingestion: Rinse mouth with water, do not induce vomiting. Get medical help right away, especially if the person feels unwell.
Suitable Extinguishing Media: Dry chemical, CO2, alcohol-resistant foam can be used. Water spray might spread the product if handled improperly.
Specific Dangers: Vapors may form explosive mixtures with air. Could emit toxic fumes of nitrogen oxides and hydrocarbons under fire conditions.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing to avoid contact with vapors and combustion products.
Advice: Keep containers cool with water spray. Avoid flushing runoff into water systems.
Personal Precautions: Wear gloves, chemical-resistant clothing, and eye protection. Work in ventilated areas or use local exhaust.
Methods for Cleanup: Absorb spillage with non-combustible, inert material like sand. Scoop up and dispose of according to regional hazardous waste protocols.
Environmental Precautions: Prevent entry into drains, soil, and water systems. Use barriers to stop further spread.
Handling: Keep away from heat and open flames. Avoid inhalation of vapors. Do not eat, drink, or smoke while handling the substance. Wash hands thoroughly after use.
Storage: Store in tightly closed containers in a cool, well-ventilated place. Keep segregated from oxidizing agents, acids, and strong alkalis. Lock up the material to keep out of reach of children or untrained personnel.
Notes: Label all containers clearly and keep an updated inventory. Regularly inspect for leaks or corrosion.
Engineering Controls: Use local exhaust ventilation where possible. Provide eyewash stations and safety showers in immediate working area.
Personal Protection: Nitrile gloves and safety goggles are recommended. In higher exposure scenarios, full face shields and respirators rated for organic vapors may become necessary.
Hygiene Measures: Regular hand washing, removal of contaminated clothing, and avoiding skin or eye contact help reduce risk. Eating and drinking near the workspace could increase oral exposure.
Appearance: Clear liquid or crystalline solid depending on storage temperature.
Odor: Ammonia-like, strong and unpleasant.
Boiling Point: 106-108°C (222-226°F)
Melting Point: -10°C to -6°C (can vary by batch)
Solubility: Soluble in water, alcohol, ether.
Vapor Pressure: Moderate at room temperature.
Flash Point: Close to 20°C (68°F), placing it among easily ignitable substances.
Density: Around 0.74–0.76 g/cm³.
Chemical Stability: Remains stable under recommended storage conditions. Breaks down in the presence of acids, strong oxidizers, or strong bases.
Hazardous Reactions: Generates hazardous nitrogen oxides and other toxic gases during combustion or decomposition. Risk of polymerization is low.
Incompatibility: Should not contact strong oxidizing agents, acids, or halogens. Risk of violent reaction or fire increases otherwise.
Acute Effects: Breathing the vapor or ingesting the compound could cause elevated heart rate, blood pressure changes, dizziness, headache, or gastrointestinal distress. Some users of supplements containing similar amines have reported agitation, irregular heartbeat, and tremor.
Sensitization: Direct skin or eye contact might result in irritation or allergic dermatitis. Prolonged exposure could increase the risk of sensitization reactions.
Chronic Exposure: Evidence in published scientific studies shows overstimulation of the central nervous system in animal models, with potential for cardiovascular damage after chronic or high-dose exposure.
Other Health Data: Not enough long-term, peer-reviewed studies address the effects in humans, so caution with regular or high-intensity exposure is best.
Toxicity: Most available data focuses on acute human risk, so full toxicological profiles for aquatic plants and animals remain limited. Conservative handling is a wise choice.
Persistence and Degradability: Organic amines can break down in soil and water over weeks or months, but bioaccumulation potential seems low.
Bioaccumulation: Unlikely to build up in animal tissues according to what’s known about similar amines.
Mobility in Soil: Likely to leach into groundwater if spilled in large amounts. Good chemical management keeps that risk in check.
Waste Handling: Collect into clearly marked hazardous waste containers. Sealing and labeling are important before handing off to professionals.
Disposal Methods: Approved combustion, incineration in compliance with local and national rules eliminates most concerns. Avoid discharge into sewer systems or open environments.
Container Disposal: Empty bottles and equipment should be rinsed and handled as hazardous until professionally cleaned or incinerated.
UN Number: Notably classed as a flammable liquid, so carries relevant shipping restrictions.
Transport Class: Flammable liquid, as per applicable regulations.
Special Precautions: Secure packaging, clearly visible hazard labels, and restricted storage near foodstuffs or oxidizers are required by best practice. Keep away from direct sunlight or sources of ignition during transport.
Workplace Regulations: Not registered as a dietary ingredient or approved medicinal substance by major regulatory bodies including the FDA or EMA. Classified as a hazardous chemical in many labor safety lists.
Consumer Product Status: Some countries have moved to ban or strictly control its presence in dietary or sports supplements due to unproven safety and doping concerns.
Reporting Obligations: Spills, injuries, or workplace exposure episodes often require notification to local environmental protection and occupational health authorities.
