Name: Butyl 3-Methoxyacetate
Chemical Formula: C7H14O3
Common Uses: Specialty solvent in paints, coatings, inks, and chemical synthesis
Physical Appearance: Clear liquid, mild odor
CAS Number: 104-03-0
Main Risks: Flammable liquid category; vapor may irritate eyes, respiratory tract, and skin; high vapor concentration can affect the nervous system; prolonged skin contact could lead to dryness or cracking
Pictograms and Symbol: Flame for flammability; exclamation mark for irritant qualities
Routes of Exposure: Inhalation, skin contact, eye contact, accidental ingestion
Immediate Concerns: Vapor can build up in poorly ventilated areas, increasing inhalation risk and explosion hazard
Main Ingredient: Butyl 3-Methoxyacetate, concentration typically above 95%
Impurities: Trace esters or alcohols from synthesis, usually below reporting thresholds
Inhalation: Move to fresh air, watch for drowsiness or headache, seek medical help if symptoms persist
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing; consider lotion or moisturizer for dry skin
Eye Contact: Rinse cautiously with water for several minutes, don’t rub eyes, medical attention if irritation continues
Ingestion: Rinse mouth, avoid inducing vomiting, seek immediate medical support if unusual symptoms show up
Fire Risk: Highly flammable liquid and vapor, so it can ignite fast from sparks or static
Extinguishing Methods: Use foam, carbon dioxide, dry chemical; water spray for cooling containers, but not direct stream
Hazardous Byproducts: Combustion may release carbon monoxide, carbon dioxide, and other toxic fumes
Protective Gear: Full protective clothing and self-contained breathing apparatus for responders due to toxic smoke
Personal Protection: Gloves, goggles, respiratory protection where vapors concentrate or spill clean-up takes time
Environmental Spills: Ventilate area, eliminate ignition sources, contain spill with absorbent like sand; avoid release into drains or waterways
Cleanup: Scoop up residue, place in sealed chemical waste containers, wash spill site when clean-up is finished
Precautions: Stop the leak if safe, restrict area, increase airflow to reduce vapor concentrations
Best Practices: Keep containers tightly closed; store in cool, dry, ventilated spots separate from oxidizers or flame
Handling Measures: Avoid breathing vapors or mists, wear suitable personal protection, ground containers to prevent static discharge; handle with care to reduce spills
Incompatibles: Strong acids, bases, and oxidizing agents could trigger reaction or fire
Storage Details: Dedicated flammable liquid storage away from open flames or hot surfaces; use compatible, properly labeled containers
Engineering Controls: Use local exhaust or general ventilation, especially when handling larger quantities; closed systems reduce risk
Protective Equipment: Chemical-resistant gloves, goggles or face shield, lab coat or apron; in poorly ventilated areas, wear an organic vapor respirator
Workplace Limits: No official regulatory exposure limits, but sticking to good ventilation and hygiene practices guards against overexposure
Hygiene: Always wash hands after use, never eat or drink in work area; remove soiled clothing straight away
Appearance: Clear, colorless to pale liquid
Odor: Mild, ether-like
Boiling Point: About 177°C (350°F)
Flash Point: Roughly 60°C (140°F), so it catches fire at moderately elevated temperatures
Solubility: Slightly soluble in water; mixes well with common organic solvents
Vapor Pressure: Low to moderate at room temperature, enough to cause buildup in closed spaces
Density: About 0.97 g/cm³
Chemical Stability: Stable under ordinary conditions, but heat or contamination can create decomposition
Conditions to Avoid: Exposure to open flame, hot surfaces, direct sunlight, incompatible chemicals like strong acids or bases
Hazardous Products: Breaks down to carbon oxides and other fumes if burned or decomposed
Polymerization: Not expected under normal handling or storage
Acute Exposure: High vapor or liquid skin contact can irritate, moderate inhalation might trigger drowsiness, headache, dizziness; extended exposure dried out skin in my experience
Long Term Effects: Chronic skin contact could make dermatitis more likely, but no widely reported cancer risk
Sensitization: No well-documented allergy potential; based on related solvents, skin dryness or mild inflammation show up faster than allergies
Ingestion Risks: Swallowing the chemical irritates digestive tract, can depress central nervous system, potentially leading to nausea or vomiting
Aquatic Impact: Low water solubility means it might float or spread, affecting aquatic organisms at certain levels
Soil Mobility: Not expected to move rapidly through soil, but spill containment is still sensible
Degradability: Biodegradation happens over time; doesn’t persist as stubbornly as heavier solvents
Bioaccumulation Risk: Low to moderate based on physical and chemical profile
Preferred Method: Send waste to licensed chemical disposal facility or hazardous waste incinerator; pouring down drains or burning in open not advised
Packaging: Put residue and clean-up media in closed, correctly labeled containers
Environmental Caution: Prevent any run-off or contamination of soil and waterways
Class: Flammable liquid for most shipping authorities
Labeling: Mark containers clearly and keep them upright; avoid rough handling that might cause leaks
Transport Conditions: Shield cargo from sources of heat or sparks; keep away from food or animal feed during shipment
Occupational Safety: Managed under workplace chemical safety regulations focused on flammable and irritant liquids
Labeling Requirements: Proper hazard and precautionary statements under GHS labeling convention
National Inventories: Registered on major chemical inventories in North America, EU, Asia-Pacific
Restrictions: No outright bans, but use in food or personal care strictly limited by chemical authorities
