Name: 2-Iodo-2-Methylpropane
Synonyms: tert-Butyl iodide
CAS Number: 75-27-4
Chemical Formula: C4H9I
Appearance: Clear, colorless to pale yellow liquid
Odor: Pungent, somewhat resembling iodine
Boiling Point: Around 83°C
Solubility: Insoluble in water, dissolves in organic solvents
Hazard Type: Flammable liquid and vapor
Acute Effects: Causes skin and eye irritation, can trigger respiratory discomfort
Chronic Effects: Iodine compounds might accumulate; persistent exposure may affect thyroid glands
Irritation: Can quickly provoke redness, stinging, or burns on exposed skin and eyes
Inhalation: Lungs may burn; headaches or dizziness can set in fast
Ingestion: Nausea, vomiting, cramps possible if swallowed
NFPA Ratings: Health - 2 | Flammability - 3 | Reactivity - 1
Chemical: 2-Iodo-2-Methylpropane
Concentration: Often used as a pure compound for laboratory purposes
Impurities: Typical lab samples contain minimal contaminants due to purification steps in production
Skin: Wash with soap and water for several minutes, remove contaminated clothing
Eyes: Rinse cautiously with water for at least 15 minutes, eyelids held open
Inhalation: Move person to fresh air, support breathing as needed
Ingestion: Rinse mouth; do not make a person vomit; seek medical advice quickly
Medical Attention: Persistent or severe symptoms should send someone to the doctor promptly
Suitable Extinguishing Media: Use carbon dioxide, foam, or dry chemical powder
Flash Point: Well below 30°C
Fire Hazards: Vapors may travel and ignite far from source, decompose to release iodine and toxic gases
Protective Equipment: Wear self-contained breathing apparatus, chemical-resistant gear
Firefighting Challenges: Runoff can pollute waterways, containers may burst under fire exposure
Spill Handling: Evacuate area, avoid inhaling fumes
Containment: Ventilate nicely, dike with sand if liquid spreads
Clean-Up: Absorb with inert material like vermiculite, shovel up for disposal
Personal Precautions: Full skin and eye protection, use respirators if ventilation’s poor
Environment: Prevent spillage from reaching drains or open soil to skirt lasting impact
Handling: Keep away from ignition sources, minimize vapor and direct contact
Personal Protection: Rubber gloves, goggles, lab coats do the trick
Storage: Cool, dry, well-ventilated area in tightly sealed bottles
Incompatibles: Strong bases, oxidizers, active metals raise risks
Add-ons: Label all containers, rotate older stock forward to reduce decomposition
Engineering Controls: Use fume hoods, local exhaust
Respiratory: NIOSH-approved respirators when vapor lingers
Skin: Chemical-resistant gloves, long sleeves, splash-proof aprons
Eyes: Tight-fitting goggles, face shields where splashing occurs
Work Practices: Wash after handling, don’t eat or drink around it
Molecular Weight: Around 184 g/mol
Physical State: Liquid under normal room conditions
Color: Clear to pale yellow
Odor: Strong, characteristic of iodine
Boiling Point: Near 83°C
Melting Point: Below room temperature
Vapor Pressure: Moderate at standard temperature
Density: Denser than water
Solubility: Resists dissolving in water but slips right into ether, alcohol, or chloroform
Volatility: Evaporates quickly, sends out noticeable odor
Stability: Reasonably stable in sealed bottles away from heat
Instabilities: Heat, UV light, and storage with air can ding shelf life
Hazardous Decomposition: Iodine vapors and carbons may form if things get too hot
Incompatible Materials: Reactive with metals, alkalis, oxidizing agents
Polymerization: Won’t set off chain reactions on its own
Acute Toxicity: Swallowing, breathing vapors, or skin contact gives moderate harm
Target Organs: Skin, eyes, respiratory system, thyroid at high doses
Symptoms: Stinging, redness, nausea, headache, possible breathing difficulty
Long-Term Effects: Extended exposure to organoiodides can disturb thyroid hormone balance
Sensitization: Skin doesn’t usually become sensitized, but caution still pays off
Persistence: Sticks around in the environment awhile if spilled
Bioaccumulation: Iodinated organics could build up in some aquatic life
Toxicity to Fish/Insects: Harmful to aquatic invertebrates at notable concentrations
Mobility: Doesn’t go far in soil, but runoff can still reach nearby streams
Degradation: Breaks down slowly outside of sunlight or strong chemical blends
Disposal: Treat as hazardous chemical waste
Methods: Incineration under controlled conditions with scrubbing for iodine
Don’t Pour Down Drains: Waterways and soil easily get tainted
Local Regulations: Follow up-to-date federal, state, or city requirements; certified handlers best choice
Container Cleaning: Triple rinse, remove all residues, clearly mark for hazardous disposal
Ground and Air: Classified as flammable liquid, special handling rules apply
Labels: Flammable, irritating, environmental hazard
Packaging: Sealed, tough-walled bottles packed within shock-absorbing crates
Precautions: Don’t ship with incompatible chemicals or oxidizers
Spillage in Transit: Emergency services should be prepped with proper containment kits
Classification: Hazardous under US OSHA and European CLP rules
Restrictions: Purchase and transport usually require responsible party documentation
Worker Protection: Must provide safety training and personal protective equipment
Environmental Release: Reporting rules in place for large accidental releases
Compliance: Stick with local and global rules on storage, signage, and disposal
