Name: Isopropyl Formate Chemical Formula: C4H8O2 CAS Number: 625-45-6 Appearance: Often shows up as a colorless liquid, sometimes with a fruity to alcoholic odor strong enough to notice in most labs or production environments. Common Uses: Used as a solvent and an intermediate in chemical synthesis, seen in industries ranging from flavor and fragrance creation to specialty organic reactions.
Hazard Class: Classified for its flammability, as well as the risk of skin, eye, or respiratory irritation. GHS Symbol: Users can expect to see a flame symbol and an exclamation mark if the bottle is labeled properly. Health Risks: Exposure can trigger symptoms like headaches, dizziness, nausea, coughing, or even burning sensations if it comes in contact with eyes or skin. Fire Risks: Flammable liquids like this catch easily and can spread flames fast, so keeping ignition sources away is critical.
Component: Isopropyl Formate Purity: Usually found in concentrations above 95% for industrial or laboratory use. Impurities: Trace levels of water, formic acid, or isopropanol may be present depending on manufacturing process and storage.
Inhalation: If someone breathes in fumes, they should step into fresh air right away. If breathing problems linger or worsen, medical attention needs to be sought out quickly. Skin Contact: Rinse the skin with running water for at least 15 minutes and remove any contaminated clothing to avoid ongoing irritation. Eye Contact: Eyes need to be flushed gently with water, keeping eyelids apart, and help from a doctor may be necessary if pain or redness keeps up. Ingestion: Rinse out the mouth with water, don’t force vomiting unless a medical professional instructs, and see a doctor as soon as possible.
Suitable Extinguishing Media: Foam, dry chemical powder, carbon dioxide, or sand should be nearby since water may spread flammable liquid fires. Specific Hazards: Burns hot and, when heated strongly, can break down to release irritant and even toxic vapors. Protection for Firefighters: Full gear, including self-contained breathing apparatus, is a must due to toxic and irritating combustion byproducts. Precautions: Remove containers from fire zone if it’s safe, and keep cooling them with water spray to avoid bursting under heat.
Personal Protection: Avoid inhaling vapors and keep skin covered. Proper gloves, safety goggles, and chemical-resistant boots are necessary. Environmental Precautions: Stop the material from entering sewers or water sources. Methods for Clean-up: Use inert absorbents like sand or vermiculite, scoop up material, and seal in chemical waste containers. Ventilate the spill area and avoid using tools that might create sparks.
Handling Precautions: Good ventilation helps cut down vapor buildup. Static discharge can light up vapors, so grounding containers and avoiding spark-prone tools is wise. Storage Conditions: Containers need to be kept sealed in cool, dry, well-ventilated areas away from flames, heat, or sunlight. Separation: Store away from acids, oxidizers, and strong bases.
Engineering Controls: Fume hoods, good exhaust, and explosion-proof electricals in spill-prone areas help lower direct risk. Personal Protective Equipment: Nitrile gloves, chemical splash goggles, and resistant lab coats or aprons prove their worth. Respiratory Protection: Cartridge respirators rated for organic vapors work if exposure levels go up or ventilation drops. Hygiene Measures: Handwashing after use and not eating or drinking in work areas clamp down on accidental ingestion or skin exposure.
Boiling Point: About 91°C Melting Point: Near -90°C Flash Point: Around 13°C Vapor Pressure: Elevated, which drives up evaporation and flammability risk. Solubility: Soluble in organic solvents, limited solubility in water. Odor: Notable, with a fruity chemical kick.
Chemical Stability: Remains steady under normal conditions if sealed and stored properly. Reactivity: Can react with strong oxidizers or acids, producing harmful vapors. Hazardous Decomposition Products: Under fire or strong heat, releases carbon monoxide, carbon dioxide, and possibly formic acid or isopropanol. Hazardous Polymerization: Not expected under regular handling.
Acute Effects: Inhaling, swallowing, or skin/eye contact can trigger irritation, headache, drowsiness, or nausea. High levels might knock the central nervous system into a fog. Chronic Effects: Regular overexposure may ramp up liver and kidney strain based on animal studies for similar esters and alcohols. Routes of Exposure: Eyes, skin, breathing, and accidental swallowing.
Aquatic Effects: Toxic to some aquatic life, especially in concentrated spills reaching waterways. Persistence: Breaks down in the environment but not without posing a threat in the short term. Bioaccumulation: Unlikely in most settings, though direct spills still threaten soil and water quality on-site.
Waste Methods: Container residues and spills should be given over to a certified hazardous waste handler. Pouring leftover solvent down the drain risks damaging water treatment and harming wildlife. Container Disposal: Empty drums or bottles need rinsing and should go to specialized recycling or incineration to prevent accidental fires or vapor release.
UN Shipping Name: Flammable Liquid, n.o.s. (contains Isopropyl Formate) UN Number: 1993 Hazard Class: 3, Flammable Liquids Packing Group: II Transport Precautions: Secure tightly, keep upright, and transport in well-ventilated vehicles away from food, feed, or active flame sources.
OSHA: Recognized as a flammable liquid and irritant in the workplace; safety plans should cover proper labeling and emergency procedures. EPA: Chemicals like this often fall under spill reporting rules if large quantities leak. Other Considerations: Employers and staff both need regular safety reviews. Location, training, and understanding label symbols make a difference in accident prevention, especially with chemicals that can catch fire quickly and trigger health symptoms at the same time.
