Name: 2,2-Dimethylheptane
Chemical Classification: Aliphatic hydrocarbon
Molecular Formula: C9H20
CAS Number: 618-45-1
Physical State: Clear, colorless liquid with a petrol-like odor
Common Uses: Laboratory research, chemical synthesis, not typically found outside regulated environments
Main Physical Hazards: Flammable liquid and vapor, presents fire and explosion risk near open flames, sparks, or hot surfaces
Health Hazards: May cause irritation to the respiratory tract, drowsiness, dizziness; prolonged skin contact can dry out or crack skin
Environmental Impact: Toxic to aquatic life and may cause long-lasting effects if significant spills enter waterways
Label Elements: Flammable symbol; Avoid inhalation, ingestion, and prolonged skin contact; Harmful if aspirated into lungs
Chemical Name: 2,2-Dimethylheptane
Concentration: Typically above 95% in research or industrial bottles
Other Components: Trace hydrocarbon impurities possible depending on production batch, but not at levels considered significant for most users
Inhalation: Remove exposed individual to fresh air, monitor symptoms like confusion or persistent headache
Skin Contact: Wash thoroughly with soap and water; remove soaked clothing to prevent further skin exposure
Eye Contact: Rinse with water for several minutes; if irritation persists, consult a medical professional
Ingestion: Seek medical help immediately; do not induce vomiting because of aspiration risk leading to lung damage
Suitable Extinguishing Media: Foam, dry chemical powder, or carbon dioxide
Fire Hazards: Vapors can form explosive mixtures with air; travels unseen to ignition sources
Protective Equipment: Full firefighting gear with self-contained breathing equipment needed
Special Instructions: Cool exposed containers with water spray to prevent explosions; approach from upwind
Spill Response: Use inert absorbent for small spills; ventilate area and prevent vapors from entering drains or sewers
Personal Protection: Gloves, safety goggles, chemical-resistant apron, and, if necessary, respirators recommended
Cleanup Approach: Remove ignition sources, contain liquid, and dispose of waste per guidelines to avoid groundwater contamination
Safe Handling Tips: Use only in well-ventilated spaces; avoid breathing vapors and prolonged skin exposure
Storage Conditions: Store in tightly closed containers in a cool, dry, well-ventilated location; keep away from strong oxidizers, open flames, or heat
Special Precautions: Ground containers during transfer, keep away from static discharge risks, and train staff on spill response
Occupational Exposure Limit: No established OSHA or ACGIH limit, though general hydrocarbon control applies
Ventilation Required: Local exhaust or fume hoods reduce airborne concentration
Protective Equipment: Chemical goggles, flame-resistant gloves, lab coat or apron; use appropriate respirator for high vapor levels
Hygiene Practices: Wash hands before eating or contacting face; avoid reutilization of contaminated clothes
Appearance: Clear, colorless liquid
Odor: Slight petrol, hydrocarbon character
Boiling Point: Approximate range from 140°C to 153°C based on available studies
Melting Point: Data reported around -90°C
Vapor Pressure: Moderate, increases with warmth; vapors heavier than air
Solubility: Insoluble in water; mixes readily with most organic solvents
Vapor Density: Heavier than air, prone to settling in enclosed or low areas
Chemical Stability: Stable at room temperature under normal storage settings
Conditions to Avoid: Open flames, sparks, static, strong oxidizing agents
Hazardous Decomposition: Carbon monoxide, carbon dioxide, possibly irritating or toxic fumes if combusted improperly
Polymerization: Does not polymerize, reduces risk of unexpected dangerous reactions
Acute Effects: Inhalation may cause headaches, lightheadedness, nausea; skin contact dries and cracks surface layers
Chronic Effects: May worsen existing respiratory or skin conditions on repeated exposure
Aspiration Risk: Small amounts entering lungs during ingestion or vomiting can cause chemical pneumonitis
Carcinogenicity: Not classified as carcinogen by major regulatory bodies; insufficient human data for specific claims
Aquatic Toxicity: Harmful to aquatic organisms at concentrations found in moderate to large chemical spills
Bioaccumulation: Expected to persist in sediments and potentially move through aquatic food webs
Environmental Fate: Breaks down slowly; low water solubility promotes compartmentalization in soils and sediments
Waste Handling: Collect unwanted product in sealed, labeled container; follow local hazardous waste protocols for incineration or chemical treatment
Environmental Stewardship: Avoid pouring into sewers or waterways; use dedicated chemical waste streams to mitigate risks
Hazard Class: Flammable liquid under most regional transport rules
Packaging Needs: Use corrosion-resistant, tightly sealed drums or bottles designed for hydrocarbons
Safety Measures: Proper labeling, grounding of containers, and restricted access during movement protect public and workers
Emergency Action: Responders should have spill kits, breathing equipment, and ensure containment away from ignition risks
Workplace Controls: Requires reporting under certain workplace safety acts where thresholds are crossed in industrial quantities
Environmental Regulations: Limits set for hydrocarbon emissions into water and air in some jurisdictions
Import and Export: Subject to customs inspection due to flammable nature, restrictions may vary between countries
