Molecular Weight: 198.26 g/mol
Synonyms: (-)-Menthyl Glyoxylate, 2-Oxo-2-[(1R,2S,5R)-5-methyl-2-(propan-2-yl)cyclohexyl]acetaldehyde
Relevant Identified Uses: Flavor/fragrance ingredient, chemical intermediate, research applications.
Inhalation: Remove to fresh air immediately. Give oxygen if breathing is difficult. Seek medical advice if symptoms persist.
Skin Contact: Rinse thoroughly with plenty of water. Remove contaminated clothing and wash before reuse. Seek medical care in case of irritation.
Eye Contact: Flush with ample water for at least 15 minutes, lifting upper and lower lids occasionally. Get medical attention if irritation continues.
Ingestion: Rinse mouth with water. Never give anything by mouth to an unconscious person. Call a physician or poison center for advice.
Important Symptoms: Burning, pain, redness, allergy in rare cases.
Suitable Extinguishing Media: CO2, dry chemical, foam, water spray (do not use direct water jet)
Unsuitable Media: High-pressure water jet, as it can spread the chemical
Specific Hazards: May release toxic or irritating vapors including carbon monoxide and carbon dioxide during combustion.
Protective Equipment: Wear full protective clothing and self-contained breathing apparatus.
Firefighters' Advice: Keep containers cool with water if possible.
Personal Precautions: Evacuate spill area. Wear gloves, chemical-resistant suit, goggles, and respiratory protection.
Environmental Precautions: Prevent entry to drains and surface water. Avoid soil contamination.
Methods for Cleaning Up: Absorb with inert earth, sand, or non-combustible material. Scoop into suitable labeled containers for disposal. Wash contaminated area with plenty of water.
Reference to Other Sections: For disposal see section on “Disposal Considerations.”
Handling: Use only in well-ventilated locations. Avoid skin and eye contact. Do not ingest or inhale vapors/mist. Keep away from ignition sources.
Storage: Store in tightly closed original containers, in cool, dry, well-ventilated area away from incompatible materials (strong oxidizers, acids, bases). Protect from direct sunlight. Recommended temperature: 2–8°C.
Incompatibilities: Strong oxidizers, acids, alkalis
Control Parameters: No established occupational exposure limits for this substance. Consider threshold values of glyoxylates in the workplace as a reference.
Engineering Controls: Local exhaust ventilation, safety shower, and eye bath in workplace.
Personal Protective Equipment: Long chemical-resistant gloves, safety goggles, impervious clothing, and NIOSH-approved respirator if airborne exposure risk present.
Hygiene Measures: Wash hands thoroughly after handling. Do not eat, drink, or smoke near work area. Remove contaminated clothes immediately.
Environmental Exposure: Use procedures to confine chemical and prevent environmental contamination.
