Chemical Name: Cycloheptanone
Synonyms: Suberone
Chemical Formula: C7H12O
Appearance: Colorless to pale yellow liquid
Odor: Mild, characteristic ketone-like smell
Common Uses: Intermediate for manufacturing pharmaceuticals and fragrances
Hazard Class: Flammable liquid, may cause irritation
Health Risks: Vapors cause drowsiness, may irritate eyes and skin with contact
Route of Entry: Inhalation, skin and eye contact, ingestion
Precautionary Statements: Avoid inhaling vapors, use protective gear, and limit environmental exposure
Main Ingredient: Cycloheptanone
CAS Number: 502-42-1
Purity: Typically above 98% for research or industrial applications
Impurities: Trace amounts of related ketones, often below detection for industrial samples
Inhalation: Move to fresh air, seek medical advice if symptoms persist
Skin Contact: Wash thoroughly using soap and water, remove contaminated clothing
Eye Contact: Rinse with plenty of clean water for several minutes, consult a healthcare provider if irritation remains
Ingestion: Rinse mouth with water, avoid inducing vomiting, obtain medical attention
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, or water spray
Hazards from Combustion: Emits irritating fumes and carbon oxides when burning
Protective Equipment: Full protective clothing and self-contained breathing apparatus for fire responders
Special Notes: Cool containers in proximity to fire with water if safe to do so, as pressure from heat may cause rupture
Personal Precautions: Use gloves, goggles, avoid breathing vapors
Spill Containment: Ventilate area well, stop spill if possible without risk
Cleanup Methods: Absorb with inert material such as sand, collect wasted material in a closed container for disposal
Environmental Cautions: Prevent liquid from entering drains, sewers, or water systems
Handling: Wear appropriate personal protective equipment to prevent skin and eye contact, and minimize vapor exposure
Storage: Keep in tightly closed container away from heat sources, store in cool, well-ventilated area
Incompatibilities: Strong oxidizers, acids, alkalis
Engineering Measures: Use fume hoods or adequate ventilation to keep airborne levels low
Personal Protection: Chemical-resistant gloves, safety goggles, protective clothing
Respiratory Protection: Use approved respirators if exposure limits exceed thresholds for air concentration
Physical State: Liquid
Color: Colorless to light yellow
Odor: Mild, sweet ketone scent
Molecular Weight: 112.17 g/mol
Boiling Point: Roughly 179 °C
Melting Point: Around -13 °C
Solubility: Slightly soluble in water, miscible with most organic solvents
Vapor Pressure: Low at room temperature
Chemical Stability: Stable under standard temperatures and conditions
Conditions to Avoid: Extreme heat, open flame, strong oxidizing agents
Decomposition Products: Carbon monoxide and carbon dioxide under combustion
Potential Reactions: May react with strong acids or bases
Acute Exposure: Inhalation leads to dizziness or headache, liquid causes skin and eye irritation
Ingestion: Can cause gastrointestinal discomfort, nausea, vomiting
Chronic Effects: Limited data on long-term toxicity, not listed as carcinogen by major regulatory bodies
Target Organs: Respiratory tract, skin, eyes
Environmental Impact: Toxic to aquatic life in concentrated form, risk of bioaccumulation considered low due to biodegradability
Mobility: Can move through soil and water via spills
Persistence: Breaks down under natural conditions, but large releases can persist and affect local ecosystems
Waste Handling: Collect unused liquid in suitable containers, dispose of in accordance with local hazardous waste regulations
Container Disposal: Triple rinse containers before discarding or recycling as chemical waste
Environmental Release: Avoid dumping in sewer systems, water bodies, or unprotected soil
UN Number: Assigned for regulated road and air transport, typically classed under ketones
Transport Hazard Class: Assigned as flammable or combustible liquid by many transport agencies
Packing Group: Usually falls within group III for lower risk chemical transport
Labeling Requirements: Clearly label containers with hazard pictograms for flammable liquid, include identification during shipping
Occupational Exposure Limits: Not broadly established, though some workplaces refer to ketone exposure guidelines
Inventory Listing: Registered on international chemical inventories, such as EINECS and TSCA
Hazard Communication: Requires clear workplace signage and training under OSHA-like regulatory systems to ensure safety
Additional Requirements: Strong recommendations for regular review of handling and transport protocols in light of evolving safety data
