Chemical Name: 1-Iodopentane
Common Synonyms: Pentyl iodide
Chemical Formula: C5H11I
CAS Number: 628-17-1
Physical Hazards: Flammable liquid, emits toxic fumes if involved in fires
Health Hazards: Skin and eye irritation, central nervous system depression possible from high vapor exposure
Warning Symbols: Harmful, flammable
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Main Ingredient: 1-Iodopentane (purity often above 97%)
Other Components: Trace organics arising from typical synthesis routes
Typical Additives: None declared in most laboratory-grade offerings
Inhalation: Move outdoors to fresh air, seek medical help if symptoms appear
Skin Contact: Wash with plenty of water and mild soap, remove contaminated clothing
Eye Contact: Rinse widely with water for several minutes, get medical advice if irritation continues
Ingestion: Rinse mouth, avoid forced vomiting, get medical assistance for significant exposure
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam for larger fires
Special Dangers: Burning releases hydrogen iodide, carbon oxides
Protective Equipment: Firefighters should use self-contained breathing apparatus and protective gear during response
Fire Hazards: Vapors can travel, ignite from distance; risk increases in unventilated spots
Personal Protection: Proper gloves, protective eyewear, avoid breathing vapors
Spill Clean-Up: Stop leak with absorbent materials such as sand or vermiculite, bag collected waste for lawful disposal
Ventilation: Open windows or boost exhausts to minimize inhalation risk
Environmental Considerations: Prevent from entering drains or waterways due to aquatic toxicity of iodinated organics
Safe Handling: Work with fume hoods or well-ventilated areas, reduce splash risk by pouring slowly
Storage Needs: Keep in tightly capped bottles, away from heat, sparks, flame, and strong oxidizers
Material Compatibility: Store separately from bases, acids, or reactive metals
Labeling: Clear hazard indication on all containers; store away from routine traffic
Engineering Controls: Local exhaust ventilation minimizes vapor build-up
Respiratory Protection: Use properly rated masks if vapors likely to exceed safe thresholds
Skin and Body Protection: Wear nitrile gloves, lab coats, close-toed shoes
Eye Protection: Safety goggles essential during handling and transfer
Appearance: Colorless to pale yellow liquid, sharp odor
Molecular Weight: 198.05 g/mol
Boiling Point: About 158°C
Melting Point: -63°C
Density: Approx. 1.66 g/cm³
Vapor Pressure: Low at room temperature but sufficient to warrant caution
Solubility: Immiscible with water, soluble in many organic solvents
Flash Point: Approximately 46°C (closed cup)
Chemical Stability: Remains stable in typical lab conditions if container sealed well
Reactive Hazards: Strong reactions with oxidizing agents or bases
Hazardous Decomposition: Yields hydrogen iodide and carbon oxides upon burning or thermal breakdown
Polymerization: Polymerization unlikely under storage or lab use scenarios
Inhalation Toxicity: Central nervous system effects can occur at high concentrations, such as dizziness, headache, even loss of consciousness
Skin and Eye Irritation: Contact triggers redness, itching, stinging or burning from extended exposure
Chronic Effects: Prolonged skin contact may worsen irritation; data on long-term effects remain limited
Ingestion Hazards: Could cause stomach discomfort, nausea, vomiting
Aquatic Toxicity: Iodinated compounds generally impact aquatic organisms; 1-Iodopentane may harm fish and invertebrates
Environmental Mobility: Dense liquid sinks, not likely to evaporate rapidly
Persistence: Slow breakdown in soil or water, potential for accumulation
Bioaccumulation: There is some evidence suggesting build-up in organisms is possible
Preferred Methods: Take to a chemical waste handling service, never flush into sinks or drains
Container Disposal: Rinse glassware or containers outdoors, triple rinse, and treat washings as hazardous
Local Laws: Strict regulations in many areas limit how much and where such chemicals enter landfill or incinerator streams
Shipping Class: Flammable liquid, may require UN identification
Packing Rules: Tightly capped, upright, shock-resistant packaging
Special Precautions: Keep away from open flames or large heat sources through whole shipping process
Incompatibilities: No oxidizers or bases during transport
Labelling Requirements: Most jurisdictions call for visible hazard labeling — flammability, health risks
Workplace Controls: Handling protocols align with hazardous substance rules in universities, chemical plants, and research labs
International Transport: Restrictions may arise due to flammable and toxic ratings under global shipping rules
Employee Rights: Worker safety guidelines guarantee training, protective gear, and disclosure of potential risks
