Chemical: 2,6-Dimethyl-5-heptenal propylene glycol acetal
Concentration: 98–100%
Impurities: Typical trace levels of starting materials or reaction byproducts
Molecular Formula: C12H24O2
Inhalation: Remove person to fresh air, provide oxygen if needed. Seek immediate medical attention for persistent discomfort.
Skin Contact: Rinse affected skin thoroughly with soap and water for at least fifteen minutes. Remove contaminated clothing and launder before reuse.
Eye Contact: Flush eyes with clean, gently flowing water for at least twenty minutes, holding eyelids apart. Seek immediate medical advice.
Ingestion: Rinse mouth, do not induce vomiting unless directed by medical personnel. Get to hospital or physician as soon as feasible.
Suitable Extinguishing Media: Dry chemical, CO2, foam, and water spray can be used;
Unsuitable Extinguishing Media: Strong water jets may spread the product
Specific Hazards: Vapors could form explosive mixtures with air under certain conditions. Burning produces toxic fumes of carbon oxides.
Protective Equipment: Firefighters need full turnout gear and self-contained breathing apparatus to prevent inhalation of vapors or combustion products.
Advice for Firefighters: Keep containers cool by spraying with water to minimize risk of explosion. Approach upwind to avoid inhaling combustion gases.
Personal Precautions: Evacuate area if a large spill occurs. Use appropriate respiratory protection to prevent inhalation of vapors.
Environmental Precautions: Prevent product from entering drains or local waterways; dike spill with non-combustible material if feasible.
Cleanup Methods: Absorb with sand, earth, or other inert material. Collect residues in suitable containers for disposal. Clean area with copious amounts of water.
Handling: Maintain good ventilation in the workplace; minimize direct contact with liquid and vapors by using proper protective equipment. Avoid sparks and open flames.
Storage Conditions: Store in a tightly closed, clearly labeled drum or container away from direct sunlight, in a cool, dry, well-ventilated place. Keep away from incompatible chemicals like strong acids, oxidizers, and alkalis.
Specific End Use: Only for use as designated by trained professionals in industrial settings.
Exposure Limits: No specific occupational exposure limits set; general industry guideline for similar compounds recommends keeping airborne concentrations below 10 ppm.
Engineering Controls: User should install local exhaust or general ventilation systems to remove vapors from work area.
Eye Protection: Wear chemical splash goggles or face shield.
Skin Protection: Wear chemical-resistant gloves (nitrile or neoprene) and long sleeves to minimize skin exposure.
Respiratory Protection: Use a properly fitted respirator (organic vapor cartridge) when handling large quantities or working in confined spaces.

Hazardous Reactions: Risk of violent reaction with strong oxidizing agents, acids, and alkalis.
Hazardous Decomposition Products: Combustion may release carbon monoxide, carbon dioxide, aldehydes, and other toxic chemicals.
Conditions to Avoid: Heat, open flame, sources of ignition, and prolonged exposure to air or sunlight.
Acute Toxicity: Low to moderate; ingestion of significant amounts may cause gastrointestinal upset or central nervous system depression.
Skin Corrosion/Irritation: Causes irritation and redness after prolonged or repeated contact.
Eye Damage/Irritation: Induces moderate irritation and tearing.
Respiratory or Skin Sensitization: Prolonged inhalation may provoke sensitization in individuals with pre-existing allergies.
Other Data: No long-term carcinogenicity, mutagenicity, or reproductive toxicity studies available.
Toxicity: Potentially harmful to aquatic organisms if released in quantity.
Persistence and Degradability: Moderate biodegradability in soil and water, breakdown products are less persistent.
Bioaccumulative Potential: Low to moderate; low potential for accumulation in aquatic life calculated based on octanol-water partitioning.
Mobility in Soil: Moderate movement expected in soil profiles; risk of groundwater contamination rises with spillage.
Other Adverse Effects: Avoid uncontrolled release to surface water as a precaution statement.
Waste Treatment Methods: Incineration in approved waste disposal plants meets regulatory standards. Small residues may be diluted and flushed to approved treatment facility provided local guidelines allow.
Container Disposal: Empty containers thoroughly and triple rinse. Dispose of in accordance with state, federal, and local environmental regulations.
Special Considerations: Do not landfill bulk quantities. Do not contaminate water, food, or feed by storage or disposal.
UN Number: Not regulated under most systems for road, sea, air transport.
