Composition / Information on Ingredients

Chemical Identity: 2-Methyl-3-Ethoxy Pyrazine
CAS Number: 18138-04-4
EC Number: [Provide EC number if available]
Purity: Typically above 97%
Impurities: Trace amounts of related pyrazines or solvents may exist depending on method of synthesis

First Aid Measures

Eye Contact: Rinse carefully with running water for several minutes; remove contact lenses, continue rinsing if irritation persists
Skin Contact: Wash skin with soap and water, remove contaminated clothing, seek medical attention for ongoing irritation
Inhalation: Remove person to fresh air, seek medical attention if symptoms like coughing or shortness of breath develop
Ingestion: Rinse mouth, do not induce vomiting, get medical help if adverse effects appear or persist

Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam
Unsuitable Extinguishing Media: Avoid using direct water stream
Specific Hazards: Vapors may be flammable, combustion produces irritating gases, oxides of nitrogen and carbon
Protective Equipment: Firefighters should wear self-contained breathing apparatus, full protective gear
Special Fire Fighting Procedures: Cool exposed containers with water spray, avoid breathing fumes

Accidental Release Measures

Personal Precautions: Use gloves, safety goggles, and appropriate respirator, ventilate the spill area
Environmental Precautions: Prevent runoff into drains, sewers, waterways, contain spill with inert absorbent
Cleanup Methods: Absorb liquid with sand or vermiculite, shovel into sealed containers for safe disposal, wash area with detergent and water after removal

Handling and Storage

Handling: Keep container tightly closed, avoid breathing mist or vapor, work in well-ventilated environments, avoid contact with skin, eyes, and clothing
Storage: Store in cool, dry, and well-ventilated area, away from sources of ignition, incompatible substances, or direct sunlight, keep containers upright and tightly sealed to prevent leaks or spills
Specific Storage Requirements: Use only non-sparking tools, ground and bond containers if transferring large amounts

Exposure Controls and Personal Protection

Exposure Limits: Not established for this specific compound, general control for nuisance dusts or vapors
Engineering Controls: Use local exhaust or general ventilation to maintain levels below recommended exposure limits
Personal Protective Equipment: Nitrile gloves, chemical-resistant safety goggles, lab coat or protective clothing, if risk of inhalation exists, use NIOSH-approved respirator
Hygiene Measures: Wash hands and face before eating, drinking, or smoking, remove contaminated clothing and wash separately before reuse

Physical and Chemical Properties

Appearance: Colorless to pale yellow liquid
Odor: Earthy, green, nutty scent, characteristic of pyrazine compounds
pH: Neutral (not readily soluble in water for pH measurement)
Melting Point: Data not readily available, typically liquid at room temperature
Boiling Point: Approx. 170-185°C
Flash Point: Above 70°C (closed cup, estimate)
Solubility: Limited in water, soluble in organic solvents like ethanol, ether
Vapor Pressure: Low at ambient temperature
Specific Gravity: 1.025–1.050 (variable by batch)
Partition Coefficient (n-octanol/water): Not determined but expected to favor organic phase
Viscosity: Thin liquid
Evaporation Rate: Moderate

Stability and Reactivity

Chemical Stability: Stable under normal storage, may degrade at high temperatures or under strong sunlight
Possibility of Hazardous Reactions: None anticipated under typical conditions, avoid contact with strong oxidizers or acids
Hazardous Decomposition Products: Nitrogen oxides, carbon monoxide, and carbon dioxide under fire conditions
Incompatible Materials: Strong acids, bases, or oxidizing agents
Conditions to Avoid: High heat, flames, static discharge, prolonged exposure to light or air leading to oxidation

Toxicological Information

Likely Routes of Exposure: Inhalation, skin or eye contact, ingestion
Acute Effects: Irritation to skin, eyes, respiratory tract; ingestion may cause stomach upset
Chronic Effects: No long-term studies available; similar pyrazines have not shown significant chronic toxicity in animals
LD50 (Oral, Rat): Not specifically measured for this compound, estimated to be moderate based on analogs
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, or OSHA
Other Information: No evidence of reproductive toxicity or mutagenicity; general caution should always apply due to lack of extensive testing

Ecological Information

Ecotoxicity: No specific data, expected to be moderately toxic to aquatic organisms based on structural similarity to other alkyl pyrazines
Persistence and Degradability: Not rapidly biodegradable, may persist in soil or water settings
Bioaccumulation Potential: Limited studies, low to moderate risk based on logP properties
Mobility in Soil: Likely to have low mobility due to low solubility in water, may adhere to organic material in soil
Other Adverse Effects: Avoid uncontrolled release to the environment; use appropriate containment and disposal methods

Disposal Considerations

Waste Disposal Methods: Dispose of in accordance with local, regional, and national regulations for chemical waste; small amounts may be diluted and incinerated by authorized facilities
Container Disposal: Triple rinse empty containers, then offer for recycling or dispose as hazardous waste
Special Precautions: Never discharge to surface waters or drainage systems, avoid disposing with regular household waste
Recommended Methods: High temperature incineration preferred, seek guidance from environmental authorities if uncertain

Transport Information

UN Number: Not classified as hazardous for transport
Transport Hazard Class: None for air, sea, or road transport under standard shipping quantities
Packing Group: Not regulated
Special Precautions: Use tightly sealed, properly labeled containers, store upright during transit to prevent leaks
Environmental Hazards: Keep away from food and feedstuffs, do not allow product to reach aquatic environments in significant quantities during shipping

Regulatory Information

Safety, Health and Environmental Regulations: Not specifically listed in major chemical inventories as hazardous, may be subject to workplace safety regulations
TSCA (USA): Listed
REACH (EU): Registration status should be confirmed
California Proposition 65: Not listed
Other National or Local Listings: Check country-specific regulatory agencies for updates or new restrictions
