Chemical Name: Suberic Acid
Concentration: Greater than 99% (technical grade and higher Purity product)
Impurities: May contain trace amounts of related dicarboxylic acids, water, and inorganic residues due to manufacturing.
Additives: No additives used in certified pure grades.
Eye Contact: Immediately rinse with plenty of water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical attention for persistent symptoms.
Skin Contact: Wash skin thoroughly with soap and water. Remove contaminated clothing and launder before reuse. If irritation persists, get medical advice.
Inhalation: Move person to fresh air, keep at rest in a position comfortable for breathing, seek medical attention if symptoms develop.
Ingestion: Rinse mouth, do not induce vomiting unless directed by medical professionals, seek medical care if you feel unwell.
Note for Physicians: Treat symptomatically based on patient’s current signs and act quickly to prevent further absorption.
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical powder, carbon dioxide.
Specific Hazards: Can form combustible dust concentrations in air. Decomposes on heating to release carbon oxides.
Protective Equipment for Firefighters: Self-contained breathing apparatus and full protective clothing required.
Firefighting Instructions: Approach fire from upwind to avoid hazardous vapors. Cool containers exposed to fire with water spray. Remove unaffected materials from fire area if safe to do so.
Personal Precautions: Use personal protective equipment including gloves, goggles, and dust mask. Evacuate non-essential personnel and ventilate area.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not allow entry into sewers or watercourses.
Methods for Cleaning Up: Sweep up and place in suitable closed containers for disposal. Use damp cloth or vacuum to reduce dust dispersal. Wash area with water after removal.
Handling: Keep away from heat, sparks, and open flame. Use only in well-ventilated areas. Avoid contact with eyes, skin, and clothing. Do not eat, drink, or smoke near handling areas. Avoid creating and breathing dust.
Storage: Store in tightly closed, labeled containers in a cool, dry, and well-ventilated area away from incompatible materials such as strong oxidants or bases. Place containers in secondary containment to prevent spillage.
Incompatibles: Reacts with strong bases and oxidizing agents. Avoid storing with acids and alkalis in close proximity.
Occupational Exposure Limits: No specific regulatory limits established for suberic acid, but control dust as for nuisance particulates.
Engineering Controls: Provide local exhaust ventilation or enclosure to control airborne dust concentrations. Use enclosed processes or isolation when feasible.
Personal Protective Equipment: Safety glasses with side shields or goggles, chemical-resistant gloves (such as PVC or nitrile), long sleeves and trousers. Use a dust respirator where dust exposure can accumulate above safe levels. Wash hands and face after handling.
Hygiene Measures: Remove contaminated clothing before leaving work area. Do not eat, drink, or smoke in work areas where substance is handled.
Appearance: White crystalline solid
Odor: Odorless or slight carboxylic acid scent
pH (5% solution): Slightly acidic
Melting Point: 141–143°C (285–289°F)
Boiling Point: Decomposes before boiling
Flash Point: Not easily flammable, but dust-air mixtures can ignite
Solubility: Slightly soluble in water and soluble in boiling water, soluble in alcohol and ether
Vapor Pressure: Negligible at room temperature
Density: 1.28 g/cm³
Partition Coefficient (log Kow): Approximately -1.29
Chemical Stability: Stable under recommended storage conditions. Will decompose at high temperatures producing fumes of carbon oxides.
Conditions to Avoid: Moisture, heat, ignition sources, and incompatible chemicals such as strong oxidants and alkalies.
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, and potentially irritating organic vapors upon combustion or thermal decomposition.
Polymerization: Not known to occur under normal handling conditions.
Routes of Exposure: Eyes, skin, inhalation, and ingestion
Acute Effects: Eye and skin irritation, mild respiratory tract discomfort after inhaling significant concentrations of dust.
Chronic Effects: No evidence of long-term health effects or sensitization provided exposure is controlled. No data indicating carcinogenicity, mutagenicity, or reproductive toxicity.
LD50 (oral, rat): >5000 mg/kg (low acute toxicity)
Symptoms: Redness, pain, possible coughing or mild nausea if inhaled or ingested in significant quantities.
Ecotoxicity: Not expected to be toxic to aquatic organisms at low concentrations. Biodegradation in soil and water occurs, but best to limit contamination.
Persistence and Degradability: Biodegradable in the environment by natural microbial activity.
Bioaccumulative Potential: Low (log Kow indicates low bioaccumulation harm)
Mobility in Soil: Expected to exhibit moderate mobility depending on local conditions.
Other Adverse Effects: Poorly soluble acids may acidify water slightly if discharged in bulk, which can disrupt local pH.
Waste Disposal Methods: Collect and contain in appropriate containers for landfill or incineration at an approved facility. Never pour waste into drains or sewers.
Contaminated Packaging: Clean and reuse where possible or dispose as hazardous chemical waste according to local, national, and regional regulations.
Precautions: Avoid creating dust during disposal, ensure proper labeling on all disposal containers, and prevent environmental contamination during transfer.
UN Number: Not regulated as a hazardous material for ground, air, or sea transport under UN, IMDG, IATA, or DOT guidelines for most industrial applications.
Proper Shipping Name: Suberic Acid, solid
Transport Hazard Class: Not classified as dangerous
Packing Group: Not applicable
Special Precautions for Transport: Keep cargo securely packaged to avoid shifting and dust generation, protect from moisture, separate from reactive substances.
