Name: Phloroglucinol
Chemical Formula: C6H6O3
Other Names: 1,3,5-Trihydroxybenzene
Appearance: White to pale yellow crystalline powder
Odor: Faint, phenolic
Physical Hazards: Not classified as flammable in typical laboratory conditions, but dust can be combustible in sufficient quantity and particle size.
Health Hazards: May cause skin and eye irritation; harmful if swallowed; can irritate respiratory tract if dust is inhaled.
Environmental Hazards: No severe aquatic toxicity identified, but responsible practices help limit impact.
Active Ingredient: Phloroglucinol (pure or technical grade)
CAS Number: 108-73-6
Impurities: Minimal in analytical and research settings.
Inhalation: Move to fresh air and monitor for any symptoms like cough or respiratory discomfort; seek medical care if persistent.
Skin Contact: Remove contaminated clothing and rinse skin with plenty of water; wash with soap to prevent irritation.
Eye Contact: Gently rinse eyes for several minutes with water; remove contact lenses if present and easy to do.
Ingestion: Rinse mouth, avoid inducing vomiting unless directed; seek immediate medical advice for any significant exposure.
Extinguishing Media: Use dry chemical, carbon dioxide, or foam. Water spray may also be effective for small fires.
Fire Hazards: Upon decomposition, can release irritating fumes like carbon oxides.
Protective Equipment: Firefighters should wear full protective gear and a self-contained breathing apparatus.
Personal Precautions: Use gloves, goggles, and a dust mask or respirator when dealing with spills.
Environmental Precautions: Prevent large quantities from entering drains or waterways; avoid overuse of water during cleanup.
Methods for Cleaning Up: Carefully scoop up dry powder and place in labeled container for disposal; ventilate area after spill.
Safe Handling: Wear appropriate personal protection; minimize generation of airborne dust.
Storage Conditions: Store in tightly closed containers, away from strong oxidizing agents. Keep in cool, dry, and well-ventilated area.
Occupational Exposure Limits: Not established by OSHA or other agencies for phloroglucinol, but avoid unnecessary dust exposure.
Engineering Controls: Use chemical fume hood or local exhaust if available.
Personal Protective Equipment: Laboratory gloves, safety goggles, lab coat; use respirator for dusty work.
Molecular Weight: 126.11 g/mol
Melting Point: Around 218°C
Solubility: Soluble in water, ethanol, and ether
Boiling Point: Decomposes before boiling
Vapor Pressure: Negligible at room temperature
Density: Approximately 1.28 g/cm³
Stability: Stable under recommended conditions; keep away from strong oxidizing agents.
Conditions to Avoid: Excessive heat, exposure to moisture, sources of ignition.
Hazardous Reactions: Can react with strong oxidizers; not likely to polymerize.
Decomposition Products: Carbon monoxide, carbon dioxide.
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion.
Symptoms: Skin and eye redness, respiratory discomfort, potential gastrointestinal upset after ingestion.
Acute Toxicity: Data from animal studies show moderate oral toxicity; precise LD50 values reported around 300-500 mg/kg for rats.
Other Sensitization/Chronic Effects: Not known to cause chronic illness, but excessive handling without protection can aggravate skin and respiratory symptoms.
Aquatic Toxicity: Low acute toxicity to fish and water organisms at levels expected from small laboratory spills.
Persistence and Degradability: Breaks down under environmental conditions over time.
Bioaccumulation: Unlikely to build up in organisms due to solubility and breakdown paths.
Waste Handling: Collect in sealed container; use licensed waste disposal facilities familiar with chemical waste.
Safe Practices: Do not flush to drains or landfill; avoid contaminating water supplies.
UN Number: Not regulated by major international transport codes as a hazardous material in small quantities.
Shipping Precautions: Use standard chemical transport containers; keep dry and segregated from incompatible substances during transport.
Inventory Listings: Included in major chemical inventories (such as the TSCA inventory in the US and EINECS in Europe).
Labels/Warnings: Standard hazard statements about irritation risk; not subject to severe restrictions at most concentrations used in laboratories.
Workplace Regulations: Routine laboratory safety procedures apply, such as mandatory PPE and chemical hygiene plan.
