Emergency Overview: Colorless, odorless liquid or solid depending on temperature; considered relatively inert but flammable
GHS Classification: Flammable Liquid, Category 2
Pictogram: Flame symbol
Signal Word: Danger
Hazard Statements: Highly flammable liquid and vapor; can cause eye and skin irritation; inhalation of vapors may cause drowsiness or dizziness
Precautionary Statements: Keep away from heat, sparks, open flames; use explosion-proof equipment; avoid inhalation and contact with skin or eyes
Target Organs: Central nervous system
Other Hazards: May accumulate static charge, handle with anti-static measures; environmental impact considered low due to relatively low toxicity in available studies
Chemical Name: 2,2,3',3'-Tetramethylbutane
Concentration: ≥99%
CAS Number: 594-82-1
Impurities: Typical laboratory grades have minimal impurities, normally lower alkanes (pentane, hexane) less than 1%
Additives: None typically present in pure laboratory stocks
Inhalation: Remove to fresh air, monitor breathing, provide artificial respiration if needed, seek medical attention if symptoms develop
Skin Contact: Wash area thoroughly with soap and water; remove contaminated clothing; rinse for at least 15 minutes
Eye Contact: Flush with plenty of water or saline for at least 15 minutes, lifting upper and lower eyelids; seek immediate medical attention if irritation persists
Ingestion: Do not induce vomiting; rinse mouth with water; seek prompt medical attention
Symptoms: Respiratory tract irritation, drowsiness, headache, possible skin redness, or eye discomfort; seek evaluation for prolonged exposure
Suitable Extinguishing Agents: Carbon dioxide, dry chemical, foam, water spray
Fire Hazards: Vapor may form explosive mixtures with air; heat or flame can cause violent ignition
Firefighting Instructions: Wear self-contained breathing apparatus and full bunker gear; cool containers with water from a safe distance
Explosion Hazards: Vapors heavier than air, can spread along floors or in confined locations; containers may burst in fire conditions
Byproducts: Carbon oxides (CO, CO2), possibly irritating and toxic fumes
Personal Precautions: Evacuate area, ventilate if possible, avoid breathing vapors, wear appropriate personal protective equipment
Methods for Clean-up: Use non-sparking tools, absorb with sand, earth, or inert material; collect into sealed waste containers
Environmental Precautions: Prevent entry into sewers or waterways; notify environmental authorities in event of significant spill
Decontamination: Ventilate area, scrub spill area with detergent and water after removal of material
Disposal: Place waste in suitable, labeled, closed containers for safe disposal per local requirements
Handling: Wear protective gloves and eye protection, prevent static discharge by grounding, handle in well-ventilated areas, do not inhale vapors or allow contact with skin and eyes, use spark-proof tools
Storage: Store in tightly closed containers, away from incompatible materials and ignition sources, in cool, dry, well-ventilated locations
Special Precautions: Keep away from oxidizers, acids, chlorine; avoid accumulation of vapors in confined spaces; ensure proper labeling
Transfer Recommendations: Use properly grounded lines and containers to avoid electrical hazards during transfer
Occupational Exposure Limits: No established OSHA or ACGIH limits, treat as aliphatic hydrocarbon vapor
Engineering Controls: Use fumehoods or local exhaust to control vapor; keep airborne concentrations low
Personal Protective Equipment (PPE): Safety glasses or chemical goggles, nitrile or neoprene gloves, flame-resistant clothing, closed-toe shoes
Respiratory Protection: Use NIOSH-approved organic vapor respirators where ventilation cannot maintain safe vapor levels
Hygiene Measures: Wash hands thoroughly after use, do not eat or drink in work areas, remove contaminated clothing and wash before reuse
Appearance: Clear, colorless liquid or solid below room temperature
Odor: Mild, gasoline-like
Molecular Weight: 114.22 g/mol
Boiling Point: Approximately 107°C (225°F)
Melting Point: Around 99°C (210°F)
Flash Point: Estimated between -1°C and 2°C (30°F - 35.6°F)
Evaporation Rate: Not established, generally rapid for low molecular hydrocarbons
Vapor Pressure: Approx. 10 mmHg at 25°C
Vapor Density: Heavier than air
Solubility: Insoluble in water, miscible with organic solvents
Partition Coefficient (n-octanol/water): Predicted log Kow > 3.7
Autoignition Temperature: Around 300°C (572°F)
Decomposition Temperature: Not specifically established, avoid strong heating
Viscosity: Low, typical of light hydrocarbons
Chemical Stability: Stable under recommended conditions of storage and handling
Conditions to Avoid: Heat, sparks, open flames, static discharge, direct sunlight
Incompatible Materials: Strong oxidizers, acids, halogens, chlorine
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, potentially other organic fragments on strong heating
Hazardous Reactions: Strong exotherm on contact with powerful oxidizers
Polymerization: Not known to occur under normal storage
Acute Toxicity: Limited animal and human toxicity data; similar aliphatic hydrocarbons suggest low acute oral and dermal toxicity
Inhalation Effects: Drowsiness, dizziness, possible headache at higher vapor concentrations, high concentrations may depress central nervous system
Skin Contact: Possible mild irritation or skin dryness
Eye Contact: May cause mild transient irritation, no evidence of long-term damage
Chronic Effects: No confirmed carcinogenic, mutagenic, or reproductive toxicity based on structure-activity relationship
Sensitization: Not expected based on data from similar hydrocarbons
Additional Risk Groups: Individuals with respiratory conditions might experience more pronounced symptoms if exposed
Ecotoxicity: Expected low toxicity to aquatic and terrestrial organisms, data from structurally similar alkanes show minimal acute effects
Persistence and Degradability: Not expected to persist significantly; breaks down slowly in air by reaction with hydroxyl radicals, more rapidly in soil
Bioaccumulation: Moderate log Kow indicates some potential for accumulation in organisms
Mobility in Soil: Likely to volatilize from soil surface; low mobility in groundwater
Other Adverse Effects: Not considered ozone depleting or persistent in the environment in significant quantities based on its volatility and degradation pathways
Waste Treatment Methods: Dispose as flammable organic chemical by licensed contractor; incineration recommended where permitted
Container Disposal: Triple rinse, puncture, and send to approved drum recycler or hazardous waste facility
Additional Notes: Comply with all local, regional, and national regulations; avoid release to the environment; do not landfill uncontainerized liquid material
UN Number: UN 1208
