CAS Number: 1009-14-9
Appearance: Clear, colorless to pale yellow liquid
Odor: Slight, aromatic
Common Use: Intermediate for organic synthesis, research applications
Physical Form: Liquid at room temperature
GHS Classification: Harmful if swallowed, causes skin and eye irritation
Hazard Statements: May cause respiratory irritation, risk of organ damage after prolonged exposure
Signal Word: Warning
Pictograms: Exclamation mark
Routes of Exposure: Inhalation, ingestion, skin absorption, eye contact
Symptoms: Irritation of eyes, nose, throat; headache, nausea at high exposure
Substance: Valerophenone
Concentration: 100% for commercially pure material
Impurities: Trace organic solvents may appear in poorly distilled samples; usually contain no additional hazardous ingredients
Inhalation: Remove to fresh air, observe for symptoms, seek medical attention if breathing difficulty persists
Skin Contact: Immediately wash with plenty of water and mild soap, remove contaminated clothing, seek medical attention for irritation
Eye Contact: Flush immediately with copious amounts of water for at least 15 minutes, hold eyelids open, consult a doctor
Ingestion: Rinse mouth, drink water if conscious, do not induce vomiting, seek medical help promptly
Fire Hazards: Flammable under certain conditions, may form explosive vapor-air mixtures
Extinguishing Media: Use carbon dioxide, dry chemical powder, foam; avoid water jets
Specific Hazards: Combustion yields carbon monoxide, carbon dioxide, and possibly irritating fumes
Protective Equipment: Firefighters need self-contained breathing apparatus and chemical-resistant gear
Personal Precautions: Evacuate area, ventilate, avoid breathing vapors, use gloves and eye protection
Environmental Precautions: Prevent product from entering drains, sewers, or watercourses
Spill Cleanup: Absorb with inert material such as sand, place in closed container, clean spill area with soap and water
Handling: Work in a fume hood for open operations, avoid skin and eye contact, keep away from heat sources or sparks
Storage: Store in tightly sealed containers, in a cool, dry, ventilated location away from incompatible chemicals like oxidizers
Storage Temperature: Preferable below 25°C
Engineering Controls: Use fume hood, ensure good laboratory ventilation
Personal Protection: Wear nitrile gloves, protective lab coat, safety goggles
Respiratory Protection: Use an approved respirator if exposure risk exists
Hygiene Measures: Wash face, hands, and exposed skin after handling
Appearance: Colorless to pale yellow liquid
Odor: Faint aromatic scent
Boiling Point: 244–247°C
Melting Point: -15°C (approximately)
Flash Point: 107°C (closed cup)
Solubility: Insoluble in water, soluble in ethanol and ether
Density: 0.982 g/cm³ at 20°C
Vapor Pressure: Low at room temperature
Stability: Stable under recommended storage and handling conditions
Reactivity: Can react with strong oxidizing agents, reducing agents, strong acids
Hazardous Decomposition: Oxides of carbon, toxic fumes developed during fire or high-temperature breakdown
Acute Toxicity: Data shows moderate toxicity by ingestion
Chronic Health Hazards: Prolonged skin contact may cause irritation, no confirmed evidence of carcinogenic effects so far
Peculiar Effects: Exposure above recommended limits may lead to headaches, dizziness, respiratory irritation; long-term studies in humans remain limited
Aquatic Toxicity: Expected to be toxic to aquatic organisms, avoid direct release to water systems
Persistence and Degradability: Likely biodegradable at moderate rate in environment, but persistence possible in low-oxygen waters
Bioaccumulation: Potential for bioaccumulation due to hydrophobic structure
Soil Mobility: Moderate mobility in soil, product can leach if exposed to rainwater
Waste Treatment: Collect residues and contaminated absorbent material in sealed chemical waste containers
Disposal Method: Send to licensed chemical disposal facility, do not dispose down drains or with household garbage
Environmental Precautions: Prevent environmental release, comply with local and national regulations on hazardous waste
UN Classification: Not listed as dangerous for most transport, but treat as hazardous chemical
Packing Group: No assigned group, special care required to prevent leaks
Precautions: Ensure sealed containers, avoid shipping with oxidizers, acids
Workplace Exposure Limits: Not workplace regulated in many regions, handle as if potential hazard exists
Labeled Hazards: Required GHS labels include health warning and signal word
Environmental Regulations: Local rules may restrict disposal and release; check regional environmental authority guidelines for compliance
Worker Protection Regulations: Laboratory use recommended under chemical hygiene plans, with training on spill and exposure procedures
