Chemical name: 2-Ethylhexylamine
Synonyms: Octan-2-ylamine
Appearance: Colorless to pale yellow liquid, slight amine odor
Chemical formula: C8H19N
CAS Number: 104-75-6
Classification: Flammable liquid, harmful if swallowed, causes skin and eye irritation, suspected of causing respiratory tract irritation
Labeling: GHS flammable, irritant
Routes of exposure: Inhalation, skin contact, eye contact, ingestion
Health effects: Breathing vapors can cause throat and lung irritation, headache, dizziness, nausea; skin absorption may cause redness, pain, burns; eye exposure can result in severe damage; ingesting triggers stomach distress, drowsiness, and potential nervous system effects
Fire hazards: Liquid can ignite easily, generates toxic gases upon burning
Environmental risks: Spills lead to water contamination, harmful to aquatic organisms
Main ingredient: 2-Ethylhexylamine
Purity: Often found above 98 percent in lab or industrial use
Impurities: Usually minimal in controlled supply lines, though stabilization agents may appear in trace amounts
Inhalation: Remove person to fresh air, keep comfortable, seek medical help for symptoms
Skin contact: Take off contaminated clothing, rinse skin with soap and water, medical attention may be needed if irritation persists
Eye contact: Flush eyes gently with water for several minutes, keep eyelids open, get prompt medical help
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical assistance
Extinguishing media: Use foam, CO2, dry chemical, or water spray; never use direct water jet, risk of spreading fire
Major hazards: Vapors mixed with air form explosive mixtures, releases toxic fumes under fire
Special gear: Firefighters wear self-contained breathing apparatus and protective suits
Precautions: Move containers from fire zone if possible, cool with water spray
Spill procedure: Evacuate area, ventilate, eliminate ignition sources, use absorbent material for small spills, collect in safe chemical waste containers
Personal protection: Wear respiratory protection, chemical-resistant gloves, goggles; avoid skin and eye contact
Environmental impact: Block entry into drains and waterways, alert authorities if widespread contamination
Handling: Use in well-ventilated space, ground and bond containers during transfer, control static discharge, avoid inhaling vapors and physical contact
Storage: Store in tightly sealed, properly labeled containers, in a cool, dry, fire-proof area, keep away from oxidizers, acids, sources of ignition
Security: Store out of reach of untrained personnel
Ventilation: Install local exhaust ventilation for processes with vapor exposure
Personal gear: Workers need barrier gloves, synthetic aprons, safety goggles, and sometimes face shields; in poorly ventilated locations, air-purifying respirators may be required
Hygiene: Wash hands before breaks and after handling, remove contaminated clothing promptly, do not eat or drink near the chemical
Exposure limits: No widely recognized legal exposure limits in some countries, so employers rely on protocol and best practices for safe use
State: Liquid at room temperature
Odor: Strong amine smell
Boiling point: Approaches 158 to 160 °C
Melting point: Well below room temperature, around -70 °C
Solubility: Limited solubility in water, mixes with alcohols and organic solvents
Density: Roughly 0.77 g/cm³ at 20 °C
Vapor pressure: Moderately volatile, so tanks need tight sealing
Flash point: Near 48 °C, so ignition risks in warm workplaces
Chemical stability: Stable under normal storage and use, but decomposes under heat and flame
Reactivity: Reacts strongly with acids and oxidizing agents, produces dangerous gases upon decomposition
Conditions to avoid: Heat, sparks, open flame, and static
Hazardous products: Burns and decomposition release nitrogen oxides and carbon monoxide, along with irritating amine vapors
Acute effects: Inhaling can cause headaches, dizziness, and coughing; skin contact gives moderate to severe irritation; eye exposure risks burns and lasting damage; ingesting causes stomach upset, vomiting, and depression of the central nervous system
Chronic risks: Repeated or prolonged contact can cause skin dryness, eczema, respiratory issues; some evidence of liver and kidney changes in animal tests
Worker observations: Heavy exposure linked to discomfort at concentrations well below levels causing unconsciousness or severe injury, so workplace monitoring proves essential
Carcinogenicity: No strong evidence that this compound causes cancer in humans, but as with other aliphatic amines, employers implement safeguards due to lack of comprehensive studies
Toxicity to aquatic life: Harmful to fish and invertebrates at concentrations seen in accidental spills
Persistence: Readily degraded by microorganisms in soil and water, but acute impacts last until breakdown
Bioaccumulation: Significant accumulation in living organisms not well documented, but short-term contamination can kill insects and amphibians
Runoff risks: Entry into streams or drains leads to visible fish deaths, stunted plant growth, and potential for surface scum formation
Waste treatment: Always send leftover material to licensed hazardous waste contractors; open-air disposal leads to fumes and neighborhood complaints
Container disposal: Clean empty containers before recycling, or hand over to certified disposal service; never reuse for food or drinking water
Environmental duty: Document every batch removed, comply with country-level and local environmental rules to prevent groundwater or air pollution
Shipping classification: Regulated as a flammable liquid
Container requirements: leak-proof drums or tanks with chemical-resistant seals and labels
Precautions: Secure containers against movement, keep away from incompatible substances, protect from heat
Emergency measures: Training for drivers and handlers includes chemical spill kit and protective gear; spill during transit calls for immediate road closure and professional cleanup
Local and global laws: Controlled under chemical safety, workplace health and safety, and environmental protection acts
Labeling: Requires clear hazard statements in local language, flammability warnings, and first aid information
Record-keeping: Employers must retain information on inventory, exposure incidents, and disposal activities
Community right-to-know: Safety data remains available to workers, first responders, and neighborhood groups with potential for chemical exposure concerns
Import and export: Some countries call for notification and compliance with international hazardous goods protocols
