Chemical Name: Monomethyl Succinate
Concentration: 95–100%
Impurities or Stabilizing Additives: Trace amounts of water, unreacted succinic acid or methyl alcohol possible depending on synthesis
Additional Components: None significant
Molecular Weight: 132.11 g/mol
Eye Contact: Rinse carefully with water for at least 10–15 minutes; remove contact lenses if present; seek medical attention for persistent irritation
Skin Contact: Wash off with plenty of soap and water; remove contaminated clothing; consult a physician for ongoing irritation
Inhalation: Move to fresh air; seek medical attention if symptoms like coughing or shortness of breath occur
Ingestion: Rinse mouth; seek medical attention if discomfort persists; do not induce vomiting unless directed by a healthcare professional
Most Important Symptoms: Redness, irritation, nausea, mild respiratory discomfort
Notes to Physician: Treat symptoms as they appear; no antidote known for monomethyl succinate exposure
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide
Unsuitable Media: High-pressure streams may spread material
Specific Hazards: Product itself is not flammable, but combustion may generate carbon dioxide and carbon monoxide
Protective Equipment for Firefighters: Use self-contained breathing apparatus and full protective gear
Special Precautions: Avoid inhalation of smoke, fumes, or combustion byproducts
Decomposition Products: Carbon monoxide, carbon dioxide, potentially minor organic acids
Explosion Sensitivity: No reports of explosive reactions under normal handling; avoid dust clouds in confined spaces
Personal Precautions: Wear gloves, protective eyewear, dust mask if powder form
Environmental Precautions: Prevent entry into drains, sewers, or waterways
Methods for Cleanup: Collect spillage with inert material like sand or vermiculite; place in tightly sealed containers for disposal
Cleaning: Rinse area with soap and water after removal of the bulk material
Emergency Procedures: Evacuate unprotected personnel; ventilate area to prevent accumulation of dust or vapors
Handling: Use only in well-ventilated spaces; avoid dust generation; prevent skin and eye contact
Storage: Keep containers tightly closed in a cool, dry, well-ventilated place; separate from strong oxidizers and acids
Packaging Materials: Store in original containers or containers compatible with organic esters
Incompatible Materials: Strong bases, strong oxidizers, moisture can affect product stability
Storage Temperature: Store below 25°C for best shelf life
Other Considerations: Avoid repeated or prolonged exposure; rotate stock regularly
Exposure Limits: No established occupational exposure limits; treat as nuisance dust or vapor
Engineering Controls: Use local exhaust ventilation or process enclosures to minimize airborne concentrations
Respiratory Protection: Disposable dust mask for powder, organic vapor cartridge mask for vapors
Hand Protection: Chemical-resistant gloves (nitrile or latex preferred)
Eye Protection: Safety goggles or chemical splash-proof glasses
Skin Protection: Lab coat or chemical-resistant apron
Hygiene Measures: Wash hands thoroughly after handling; avoid eating or drinking in work area
Appearance: White to off-white solid or crystalline powder
Odor: Slight, faint ester-like scent
pH: Not available for pure solid; slightly acidic in solution
Melting Point: 50–55°C

Auto-ignition Temperature: Not determined
Vapor Pressure: Negligible at room temperature
Solubility: Moderately soluble in water and most organic solvents
Density: Approximately 1.3 g/cm³
Partition Coefficient (log Kow): Estimated < 1
Viscosity: Not applicable for solid
Stability: Monomethyl succinate remains stable under normal handling and storage
Conditions to Avoid: Excess heat, exposure to high humidity or water, contact with oxidizing agents
Incompatible Materials: Strong oxidizers, strong bases, strong acids
Hazardous Decomposition Products: Carbon oxides, low molecular weight organic acids on combustion
Polymerization: No hazardous polymerization expected under normal conditions
Acute Toxicity: Low oral and dermal toxicity expected
LD50 Oral (rat): >2000 mg/kg (estimated based on structurally similar compounds)
Skin Corrosion/Irritation: Mild skin irritation possible upon prolonged or repeated exposure
Eye Damage/Irritation: Mild to moderate eye irritation can occur
Respiratory Sensitization: Dust may cause temporary respiratory discomfort
Delayed/Chronic Effects: No known chronic health effects or carcinogenicity
Other Effects: No evidence for mutagenicity or reproductive toxicity in available studies
Target Organs: None specifically identified
Ecotoxicity: Low toxicity to aquatic organisms based on available data
Persistence and Degradability: Readily biodegradable in the environment
Bioaccumulative Potential: Low potential for bioaccumulation; expected to hydrolyze in water
Mobility in Soil: Likely to exhibit moderate mobility due to solubility
Other Adverse Effects: No significant environmental risk at typical discharge levels
Disposal Methods: Dispose of in accordance with local, regional, and national regulations; use licensed waste disposal contractors
Uncontaminated Material: Consider recovery or reuse if practicable
