Chemical Name: 2-Methyl-1-Pentanol
Synonyms: 2-Methylpentan-1-ol
Molecular Formula: C6H14O
CAS Number: 105-30-6
Physical Appearance: Colorless liquid, mild alcoholic odor
Common Uses: Solvent in organic synthesis, chemical intermediate, fragrance component
Health Hazards: Irritation to eyes, skin, and respiratory tract; potential for central nervous system effects with excessive inhalation
Environmental Hazards: Harmful to aquatic organisms in concentrated spills
Fire Hazards: Flammable, forms hazardous decomposition products if burned
GHS Classification: Eye and skin irritant; specific target organ toxicity with prolonged exposure
Main Ingredient: 2-Methyl-1-Pentanol (approx. 99%)
Impurities: Trace amounts of related alcohols or hydrocarbons may be present depending on manufacturing process
Inhalation: Move to fresh air, seek medical attention if symptoms like dizziness or headache persist
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing
Eye Contact: Rinse cautiously with water for several minutes, consult a physician if irritation develops
Ingestion: Rinse mouth, do not induce vomiting, get medical advice immediately
Extinguishing Media: Use foam, dry chemical, or carbon dioxide for small fires; water spray may be used for cooling containers
Specific Hazards: Can release toxic vapors such as carbon monoxide and carbon dioxide on burning
Protective Equipment: Firefighters should use self-contained breathing apparatus and protective clothing
Personal Precautions: Avoid inhalation and contact with skin or eyes; ventilate area
Environmental Precautions: Do not allow large amounts to enter waterways; contain spillage with sand or earth
Clean-Up Methods: Soak up with inert absorbent, shovel into appropriate container; ventilate and clean area after removal
Handling: Wear suitable protective gloves and eye protection; avoid inhaling vapors or mists
Storage: Keep tightly closed in a cool, well-ventilated space away from ignition sources and strong oxidizers
Incompatibilities: Strong acids, bases, and oxidizing agents due to risk of reaction and decomposition
Engineering Controls: Use with exhaust ventilation to prevent vapor accumulation, especially in enclosed areas
Personal Protection: Chemical-resistant gloves, protective goggles, long sleeves, and if exposure limits might be exceeded, respiratory protection
Exposure Limits: No specific legal limits widely published, but minimize exposure as with similar alcohols
Boiling Point: Roughly 146–149°C
Melting Point: -70°C
Density: 0.81 g/cm³ at 20°C
Solubility: Slightly soluble in water; readily soluble in alcohols and ethers
Vapor Pressure: Low at room temperature
Odor: Mild, alcoholic
Stability: Stable under recommended handling and storage
Hazardous Reactions: Reacts with strong oxidizers, possible risk of fire and formation of hazardous byproducts
Decomposition: Burning produces carbon monoxide, carbon dioxide, possibly organic acids
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Immediate Effects: Irritation to mucous membranes; moderate toxicity if ingested in quantity
Chronic Effects: Prolonged contact may cause dermatitis
Acute Oral Toxicity (LD50, rat): 2470 mg/kg as referenced by chemical literature
Symptoms of Overexposure: Headache, drowsiness, CNS depression in high levels
Persistence and Degradability: Biodegradable in soil and water under standard conditions
Bioaccumulation: Not highly bioaccumulative due to rapid breakdown by microorganisms
Aquatic Toxicity: Harmful to aquatic life in concentrated spills; long-term impact not significant at low environmental levels
Recommended Disposal: Handled through licensed hazardous waste disposal companies
Avoid Release: Never dispose directly to sewage, surface water, or soil
Container Disposal: Empty containers should be rinsed and recycled or disposed of according to local regulations
UN Number: Not typically assigned
Hazard Class: Flammable liquid under specific regulatory frameworks, not always classified as such below certain volumes
Packing Group: Not generally regulated for small quantities; bulk shipments need assessment under national and international rules
Labeling: Clearly labeled with hazard pictograms and warnings
Regulations: Covered under standard workplace chemical safety laws, inclusion on inventories like TSCA, REACH
Employer Obligations: Provide training on safe handling, ensure up-to-date hazard communication practices, monitor spill or incident response plans
