Skin Contact: Remove any contaminated clothing, wash area thoroughly with soap and water, don’t scrub hard, get medical attention if redness or discomfort sticks around
Ingestion: Rinse mouth, give the person water to drink, don’t force vomiting, watch for dizziness or nausea, get professional help
Most Important Symptoms: Eyes sting, skin turns red or itches, throat feels scratchy or chest feels tight, nausea
Notes for Doctor: Treat symptoms as seen, no exact antidote for 2-Methoxy Pyrazine, apply general supportive care
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Methods: High-pressure water jets may spread the liquid
Specific Hazards: Vapors can travel, reach ignition sources, flash back; when burning, releases toxic fumes like nitrogen oxides and carbon monoxide
Special Protective Equipment: Self-contained breathing apparatus, chemical-resistant gear, avoid inhaling fumes
Other Advice: Keep drums cool by spraying with water, hold back from spill site unless fully geared, clear non-responders from the area
Personal Precautions: Ventilate space, remove all ignition sources, put on gloves and goggles, wear a fitted mask if vapor lingers
Environmental Precautions: Don’t pour down drains or waterways, use barriers to contain the spill
Spill Cleanup: Mop up with inert absorbents like sand or vermiculite, collect and seal waste in drums, clean the surface thoroughly
Further Actions: Call trained crew for big spills, dispose as advised by authorities
Handling: Work in well-ventilated spaces, keep away from open flames and heat, avoid spilling, close all containers tightly after use, stop vapor buildup by using local exhaust if possible
General Hygiene: Wash hands after touching, avoid eating or smoking near the chemical, change contaminated clothes
Storage: Store in original container, keep in a cool, dry spot away from sunlight and strong oxidizers, label all storage containers, don’t stack heavy materials on it
Exposure Limits: No specific OSHA or ACGIH exposure limits, keep exposure low by good ventilation
Engineering Controls: Use chemical fume hoods or exhaust fans, keep workplace air moving, close containers tightly
Personal Protective Equipment: Splash-proof goggles, chemical-resistant gloves (nitrile or neoprene), long sleeves or lab coats, proper shoes, NIOSH-certified respirators for heavy vapor
Work Practices: Don’t touch eyes or face with dirty hands, remove gloves and wash up after tasks
Other Controls: Eye-wash stations and safety showers should stand ready nearby
Appearance: Colorless to pale yellow liquid
Odor: Strong, earthy, green bell pepper scent
Odor Threshold: Very low, detectable in parts per trillion
pH: Not measurable (soluble in water)
Melting Point: -13 °C (8.6 °F)
Boiling Point: 155 °C (311 °F)
Flash Point: 55 °C (closed cup)
Evaporation Rate: Not available
Flammability: Liquid, vapors can ignite
Upper/Lower Flammable Limit: Not established
Vapor Pressure: 1.5 mm Hg at 20 °C
Vapor Density: Heavier than air
Specific Gravity: 1.09 (water = 1)
Solubility (Water): Limited
Partition Coefficient (n-octanol/water): log Kow 1.43
Auto-ignition Temperature: Not measured
Decomposition Temperature: Not measured
Viscosity: Not reported
Chemical Stability: Stays stable under normal handling conditions, reacts only if exposed to strong oxidizers
Reactivity: Does not react much with most chemicals if stored right, avoid mixing with peroxides, nitric acids, or strong alkalis
Hazardous Reactions: Unlikely unless severely overheated or in contact with strong oxidizers
Conditions to Avoid: Heat, sparks, open flames, direct sunlight
Decomposition Products: When breaking down, releases carbon monoxide, carbon dioxide, nitrogen oxides
Polymerization: Will not occur spontaneously
Acute Toxicity: Swallowing small amounts can bring nausea, vomiting, or discomfort; LD50 (oral, rat): 260 mg/kg
Skin Corrosion/Irritation: Skin reddens or itches with long contact, not classified as corrosive
Serious Eye Damage/Irritation: Causes eye stinging, redness, watering
Respiratory Sensitization: Breathing in vapors can irritate nose and throat
Skin Sensitization: Repeated contact can cause local irritation
Chronic Effects: Not proven to cause cancer, reproductive toxicity, or genetic damage based on animal tests
Other Information: No clear evidence for organ damage from low exposure, effects mostly mild unless exposed at high levels
Ecotoxicity: Toxic to some aquatic life, low doses can upset natural microbes, fish or plants in lab tests
Persistence and Degradability: Not harshly persistent, likely break downs by bacteria in soil or water with time
Bioaccumulation: Low risk due to moderate water solubility and moderate log Kow
Mobility in Soil: Travels with groundwater if spilled, doesn’t bind tightly to dirt
Other Effects: No data on ozone, greenhouse, or special local ecosystem threat
Waste Disposal: Treat as hazardous waste, collect in closed drums or tanks, hand over to properly licensed waste handlers
Contaminated Packaging: Clean drums well before reuse, if not possible, dispose with chemical waste
Other Disposal Guidance: Never pour into drains or water sources, contact local waste authority for lab waste handling, obey federal and state rules
