GHS Classification: Flammable liquid (Category 2); Acute Toxicity – Inhalation, Category 4; Skin Irritation, Category 2; Eye Irritation, Category 2A
Label Elements: Signal word: Danger; Hazard pictograms: flame, exclamation mark
Hazard Statements: Highly flammable liquid and vapor; May cause skin and eye irritation; Harmful if inhaled; May cause drowsiness or dizziness
Precautionary Statements: Keep away from heat, sparks, open flames; No smoking; Use explosion-proof equipment; Wear protective gloves, clothing, eye and face protection; Avoid breathing vapors; Use only outdoors or in well-ventilated area
Chemical: N-Propylcyclopentane
CAS Number: 15890-35-6
Concentration: 98–100%
Impurities: Small quantities of other cyclopentane derivatives or hydrocarbons possible, depending on synthesis source
Inhalation: Remove person to fresh air; seek medical attention if symptoms like headache, dizziness, or nausea occur
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, lifting eyelids occasionally; consult a physician
Skin Contact: Wash off with soap and water; remove contaminated clothing; medical attention for irritation or persistent redness
Ingestion: Rinse mouth with water; do not induce vomiting; seek medical help immediately; keep person calm
Most Important Symptoms: Drowsiness, dizziness, irritation of eyes and skin, respiratory tract irritation
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, foam, or water fog
Specific Hazards: Releases flammable vapors that can form explosive mixtures with air; vapors may travel and ignite at a distance
Special Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus
Hazardous Combustion Products: Carbon oxides, irritating gases
Advice for Firefighters: Cool containers with water spray; evacuate area; do not allow runoff to reach sewers or waterways
Personal Precautions: Evacuate area; eliminate ignition sources; ventilate area; wear protective clothing and gloves
Environmental Precautions: Prevent spillage from entering drains, watercourses, and soil
Methods for Cleanup: Contain spillage with inert absorbent (sand, earth); collect in secure, non-sparking containers for disposal; clean area thoroughly afterward; wash with soap and water for small spills
Handling: Avoid contact with skin, eyes, and clothing; handle in well-ventilated areas; prevent buildup of static electricity by grounding equipment; use personal protective equipment to avoid inhalation and accidental contact
Storage: Store in tightly closed containers in a cool, dry, well-ventilated area away from heat, sparks, open flame, or other ignition sources; keep containers grounded and properly labeled
Exposure Limits: OSHA PEL not established for this compound; best to limit exposure by industrial hygiene standards, aiming for total hydrocarbons under 300 ppm
Engineering Controls: Use local exhaust ventilation or process enclosure to keep vapor concentrations below occupational exposure limits
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash-proof goggles or face shield, flame-resistant lab coat or apron, suitable respiratory protection if ventilation is inadequate or exposure limits exceeded
Appearance: Colorless liquid
Odor: Slight hydrocarbon odor
Odor Threshold: No data available; typically detectable at ppm levels
pH: Not applicable (non-aqueous)
Melting Point/Freezing Point: -100°C (typical)
Boiling Point/Range: 104-108°C
Flash Point: Approx. 10°C (closed cup)
Evaporation Rate: Moderate (comparable to pentane or hexane)
Flammability: Highly flammable
Upper/Lower Flammability Limits: 1.4–8.7% (estimated)
Vapor Pressure: 35 mmHg at 25°C
Vapor Density: >1 (air = 1)
Relative Density: 0.75 (water = 1)
Solubility in Water: Practically insoluble
Partition Coefficient n-octanol/water (log Pow): Approx. 4.5
Autoignition Temperature: 240°C
Decomposition Temperature: No reliable data
Viscosity: Low (mobile liquid)
Chemical Stability: Stable under normal conditions; poses fire and explosion risk in presence of ignition sources
Conditions to Avoid: High heat, sparks, static discharge, open flames, oxidizing conditions
Incompatible Materials: Strong oxidizing agents, acids, halogens
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, smoke, and potentially toxic fumes during combustion
Possibility of Hazardous Reactions: Not prone to dangerous polymerization; may react with oxidizers, creating fire risk
Acute Toxicity: Inhalation of high vapor concentrations causes narcotic effects, dizziness, or even unconsciousness; oral LD50 (rat) not available, but estimated to be similar to cyclopentanes (approx. 3 g/kg)
Skin Corrosion/Irritation: Prolonged or repeated contact may cause irritation, redness, and dryness
Eye Damage/Irritation: Causes moderate irritation upon exposure
Respiratory Effects: Breathing vapors can cause respiratory tract irritation, headaches, drowsiness
Chronic Effects: Long-term exposure to hydrocarbon solvents may damage nervous system, liver, or kidneys
Carcinogenicity: Not classified as carcinogen by OSHA, IARC, or NTP
Ecotoxicity: Harmful to aquatic life; toxic to fish and invertebrates at low concentrations
Persistence and Degradability: Readily evaporates; slowly biodegrades in soil and water environments
Bioaccumulative Potential: High log Pow suggests significant potential to bioaccumulate in aquatic organisms
Mobility in Soil: Low solubility in water and high volatility promote rapid movement through air but limited soil mobility
Other Adverse Effects: Large spills create hydrocarbon sheen on water; risk to local ecosystems if released in large quantities
Waste Treatment: Treat as a hazardous chemical waste; collect in sealed, labeled drum for incineration at an approved facility
Disposal Methods: Do not pour down drains or release to environment; consult local, state, or national regulations for guidance
Contaminated Packaging: Dispose of empty containers as hazardous waste after thorough cleaning; avoid puncturing or incinerating containers before cleaning
Precautions: Spilled material should be collected by trained personnel only, wearing suitable personal protective equipment
