Synonyms: Nitrous Acid, Ethyl Ester Solution in Alcohol
CAS Number: 109-95-5 (Ethyl Nitrite)
Recommended Use: Laboratory reagent, chemical synthesis
Manufacturer/Supplier: Contact local supplier or authorized distributor
Emergency Contact: Utilize emergency response number provided by supplier or on label
Classification: Flammable liquid, acute toxicity (oral and inhalation), specific target organ toxicity, skin and eye irritant
Signal Word: Danger
Hazard Statements: Highly flammable; toxic if swallowed, inhaled, or absorbed through skin; causes eye irritation; may damage organs through prolonged or repeated exposure
Precautionary Statements: Wear protective gloves, clothing, and eye protection; keep away from heat, sparks, and open flame; use only under fume hood or with adequate ventilation; avoid all contact with liquid or vapor
Hazard Symbols: Flame, skull and crossbones, exclamation mark
Ethyl Nitrite: 5-20% (CAS 109-95-5)
Ethanol: 80-95% (CAS 64-17-5)
Impurities: Trace stabilizers or inhibitors possibly present; consult supplier for detailed analysis
Inhalation: Move person to fresh air right away, support breathing as needed, seek medical attention if symptoms like headache, dizziness, or shortness of breath occur
Skin Contact: Rinse thoroughly with water, remove contaminated clothing, wash exposed area with soap, seek medical help for irritation or burns
Eye Contact: Rinse eyes gently under water for at least 15 minutes, lift eyelids, seek immediate medical attention
Ingestion: Do not induce vomiting, rinse mouth, seek prompt medical attention; never give anything by mouth to an unconscious person
Most Important Symptoms/Effects: Breathing trouble, headaches, skin and eye irritation, confusion; risk of serious health effects with high exposure
Suitable Extinguishing Media: Use carbon dioxide, dry chemical, or foam extinguishers; avoid direct water streams
Special Hazards: Vapors can form explosive mixtures with air; combustion may create toxic gases including nitrogen oxides and carbon monoxide
Fire-Fighting Procedures: Wear self-contained breathing apparatus and full protective gear; cool containers with water from safe distance; remove containers from fire area when possible
Unusual Fire Hazards: High vapor pressure increases risk further away from source; containers may rupture with heat build-up
Personal Precautions: Evacuate area, ventilate, avoid inhalation, prevent personal contact, don protective equipment
Environmental Precautions: Prevent from entering drains, waterways, or soil; contain spills with inert absorbent material; notify appropriate emergency responders
Cleanup Methods: Absorb with sand or earth, collect into labeled waste containers, decontaminate spill area after removal
Handling: Use in well-ventilated spaces, keep away from ignition sources, ground all equipment, avoid spillage, do not breathe vapors, avoid skin and eye contact
Storage: Store in tightly closed, properly labeled containers in cool, dry, and well-ventilated locations away from heat, direct sunlight, acids, oxidizers, and incompatible chemicals
Special Considerations: Secure access, use flame arrestors as needed, regularly inspect containers for integrity, keep spill response materials available
Engineering Controls: Use chemical fume hoods or local exhaust systems, maintain negative pressure, monitor air levels
Personal Protective Equipment: Wear chemical-resistant gloves, aprons, splash goggles, and respiratory protection (NIOSH-approved) for high vapor environments or insufficient ventilation
Occupational Exposure Limits: Ethyl Nitrite—consult country or organization standards; Ethanol (OSHA PEL: 1000 ppm, ACGIH TLV: 1000 ppm)
Work Hygiene Practices: Wash hands before eating or drinking, remove soiled clothing promptly, never consume food or beverages in chemical use areas
Appearance: Clear, colorless or pale yellow liquid
Odor: Fruity, sharp, intensely sweet
pH: Not applicable (non aqueous)
Boiling Point: 78–90°C (ethanol solvent dominant)
Melting Point: Well below 0°C
Flash Point: Approximately 12°C (ethanol)
Flammability: Highly flammable liquid and vapor
Vapor Pressure: High, >40 mmHg at 20°C
Solubility: Soluble in alcohol; miscible with water; potential to release toxic vapors
Relative Density: About 0.79 (water = 1)
Chemical Stability: Tends to decompose over time, especially when exposed to light, heat, air, or moisture
Conditions to Avoid: Flames, sparks, elevated temperatures, direct sunlight, oxidizing agents, acids, and bases
Incompatible Materials: Strong oxidizers, acids, alkalis, reducing agents, halogens
Decomposition Products: Nitrogen oxides, ethanol fumes, toxic gases
Reactivity: Can react violently with some chemicals; use caution with mixing or transfer processes
Likely Routes of Exposure: Inhalation, ingestion, skin and eye contact
Symptoms of Exposure: Severe headache, dizziness, weakness, nausea, blue coloring of lips or skin (methemoglobinemia), rapid heartbeat, confusion, unconsciousness in serious cases
Acute Toxicity: Toxic by all routes; oral LD50 (rat): 160 mg/kg (ethyl nitrite); may cause respiratory paralysis or cardiac arrest with high doses
Chronic Effects: Long-term exposure may damage blood, kidneys, or liver; repeated skin contact may cause dermatitis; inhalation may cause lung irritation
Carcinogenicity: Not classified as a carcinogen by NTP, IARC, or OSHA; long-term health impact research ongoing
Aquatic Toxicity: Toxic to aquatic life even in small quantities; ethanol may contribute to oxygen depletion, ethyl nitrite is especially dangerous to fish or aquatic invertebrates
Persistence and Degradability: Ethyl nitrite hydrolyzes and volatilizes rapidly; ethanol biodegrades readily but poses oxygen demand on waterways
Bioaccumulation Potential: Low, breaks down quickly in most environmental compartments
Soil Mobility: Significant, may leach through soil into water tables, especially in case of spills
Other Harmful Effects: Alters local microbial populations, worsens eutrophication risks, impacts water quality and aquatic food webs
Waste Disposal: Collect all wastes in sealed, clearly labeled containers, do not pour down drains or release into environment, handle as hazardous waste
Method: Submit for incineration at licensed chemical waste facility, consult local and federal hazardous waste disposal guidelines
Contaminated Packaging: Wash containers prior to disposal or recycle by approved facilities; do not reuse empty chemical containers; treat as regulated hazardous material
UN Number: UN1170 (Ethanol Solution), may also require special classification as Toxic Liquid, Organic, N.O.S.
Proper Shipping Name: Ethanol Solutions or Ethyl Nitrite in Alcohol
Transport Hazard Class: 3 (Flammable liquid), subsidiary risk: toxic
Packing Group: II
Labels Required: Flammable liquid, Toxic
Transport Precautions: Secure containers, no leakage, permit-licensed handlers for large quantities, emergency spill protocols available for transport events
U.S. Regulations: SARA 311/312: Immediate (acute) health hazard, fire hazard; CERCLA: not specifically listed but regulated as hazardous; TSCA: all components listed
EU Regulations: Classified under CLP Regulation (EC) No. 1272/2008, hazardous by GHS standards
Canada: WHMIS Classification: B2 (Flammable), D1B (Toxic)
