Chemical Name: 1-Iodo-2-methylpropane
Synonyms: Isobutyl iodide
CAS Number: 513-38-2
Physical Appearance: Colorless to pale yellow liquid
Odor: Characteristic, sweet-like
Molecular Formula: C4H9I
Molecular Weight: about 184.0 g/mol
Main Hazards: Harmful if inhaled, swallowed, or absorbed through skin; causes irritation to eyes, skin, and respiratory system
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: Irritation of mucous membranes and skin, headache, dizziness, possible nausea on high exposure
Potential Chronic Effects: Prolonged contact could damage organs; repeated exposure risks are not fully established
Symbol: GHS06 (Skull and crossbones) and GHS07 (Exclamation mark)
Precautionary Statements: Avoid breathing vapors, prevent contact with skin and eyes, ensure good ventilation
Component: 1-Iodo-2-methylpropane
Concentration: 100% (pure)
Impurities: Usually present in trace amounts if any, but always check supplier-specific certificates
Inhalation: Move person to fresh air, stay with them, supervise for symptoms such as cough, headache, and seek medical attention if breathing troubles develop
Skin Contact: Remove any contaminated clothing, rinse skin thoroughly with water, get medical assistance if irritation persists
Eye Contact: Rinse thoroughly for several minutes, pull eyelids open to flush, remove contact lenses if present, continue rinsing and consult a physician
Ingestion: Rinse mouth, never induce vomiting unless medical staff advise, seek medical help immediately
Suitable Extinguishing Media: Dry chemical powder, foam, carbon dioxide for small fires, water spray for large quantities, but avoid direct water stream on burning liquid
Hazardous Combustion Products: Releases hydrogen iodide gas and possibly carbon oxides on burning
Protective Equipment: Wear full firefighting gear including self-contained breathing apparatus to avoid exposure to smoke and harmful gases
Fire-fighting Instructions: Move unwelcome people out, cool exposed containers with water to prevent rupture, stay upwind from toxic gases
Personal Precautions: Use gloves, protective eyewear, and respirators if available; ventilate area to avoid vapor accumulation
Environmental Precautions: Prevent chemical from entering drains, surface water or soil as iodinated hydrocarbons harm aquatic life
Containment: Stop leak if safe, use inert absorbents (sand, vermiculite), scoop up carefully, keep waste separate for safe disposal
Clean-up Procedures: Wash spill area with lots of water after picking up the material, dispose of waste as hazardous
Handling: Keep away from open flames, hot surfaces, spark-producing equipment; avoid inhaling vapors, direct contact with skin, keep containers closed unless using
Hygiene Practices: Wash hands thoroughly after handling, don’t eat, drink, or smoke in working area
Storage: Store in tightly sealed containers, keep in a cool, dry, well-ventilated place away from sunlight; segregate from incompatible chemicals, especially strong oxidizers and bases
Ventilation: Use fume hoods or exhaust fans to keep vapor levels low
Personal Protective Equipment: Wear chemical goggles, nitrile or neoprene gloves, protective lab coats
Respiratory Protection: Use organic vapor respirators if ventilation can’t remove fumes
Exposure Limits: No official OSHA or ACGIH values, but similar iodoalkanes suggest keeping exposure as low as possible; regularly monitor air if used in bulk
Appearance: Colorless to pale yellow liquid
Odor: Mild, sweet-ish
Boiling Point: Near 107°C
Melting Point: Below -60°C
Flash Point: Around 35°C (closed cup)
Solubility: Insoluble in water, soluble in organic solvents (alcohol, ether)
Vapor Pressure: Moderate at room temperature, which increases inhalation hazard
Density: About 1.59 g/cm³
Stability: Stable under recommended handling and storage conditions
Incompatible Materials: Strong oxidizing agents, alkalies, amines, strong acids; generates hazardous vapors with some metals
Hazardous Decomposition: Thermally decomposes to hydrogen iodide, carbon monoxide/dioxide
Polymerization: Not likely but avoid sharing storage with reactive substances
Likely Exposure Effects: Inhalation or skin exposure may irritate tissues, cause dizziness, headache, possibly kidney or liver stress with repeated high doses
LD50/LC50: Data is scarce; aliphatic iodoalkanes often show acute toxicity in animals, so treat with care
Symptoms of Overexposure: Headache, fatigue, nausea, skin redness, respiratory tract irritation
Long Term Risks: Chronic exposure effects poorly understood; literature warns of thyroid interference and organ damage from iodinated compounds in general
Aquatic Impact: Toxic to aquatic life, particularly to fish and invertebrates; can bioaccumulate in sensitive species
Persistence: Not expected to break down rapidly in the environment; presents risk to surface water and soil
Disposal of Spills: Must avoid letting product wash into natural water sources; hazardous waste procedures should always apply
Waste Management: Handle as hazardous chemical waste; collect in compatible, labelled containers
Treatment: Professional chemical disposal, incineration in approved facilities
Avoid: Pouring into general waste, drains, or open landfill to minimize risk for human, animal, and environmental health
Hazard Class: Flammable liquid, toxic by inhalation and contact, so regulated in shipping
Packing Group: Usually falls into medium-risk categories for transport
Precautions: Use robust packaging, avoid temperature extremes, isolate from food and feedstuffs in transit
Spill Procedures: Emergency response procedures must be available during shipping
Regulation: Listed as hazardous substance in many jurisdictions; special labelling and workplace controls often mandated
Restriction: Reference national inventories and workplace exposure limits; common for workplace health and safety rules to apply
Environmental Rules: Release or disposal often controlled to minimize environmental burden; local, national, and international controls shape how this chemical circulates
