Ethyl Formate CAS 109-94-4

1. Ethyl formate is primarily used as a fumigant and pesticide in agriculture, particularly for controlling insects in stored grain and dried fruits, serving as an alternative to methyl bromide . It also acts as a flavoring agent in the food industry, providing a fruity (rum-like) flavor to beverages, candies, and baked goods .
2. Ethyl formate CAS 109-94-4 is widely employed as a solvent in organic synthesis for cellulose nitrate, cellulose acetate, greases, and oils, and as a reagent in the formylation of carbanions .
3. Applications of Ethyl formate also include its use in the perfume and fragrance industry for its pleasant aroma, in biotechnology for extraction and purification processes, and as a research chemical for studying lipase-catalyzed reactions .

1. Store Ethyl formate in a tightly sealed container in a cool, dry, and well-ventilated area, away from heat, sparks, and open flames; recommended storage is at room temperature (below 30°C) and protected from moisture . Keep container grounded and bonded to prevent electrostatic discharge .
2. Keep Ethyl formate strictly away from strong oxidizing agents, strong acids, strong bases, and nitrates, as Ethyl formate CAS 109-94-4 is incompatible and can react violently with these materials .
3. Always use Ethyl formate CAS 109-94-4 appropriate personal protective equipment (PPE) including chemical-resistant gloves (butyl-rubber), safety goggles, and protective clothing; use only with explosion-proof equipment and adequate ventilation in a fume hood to avoid breathing vapors .

1. Immediately isolate the spill area (at least 50 meters in all directions), eliminate all ignition sources, and ensure adequate ventilation; contain Ethyl formate using inert, non-combustible absorbent material (e.g., dry sand) and prevent entry into drains or waterways . Risk of explosion; do NOT wash away into sewer .
2. Carefully collect Ethyl formate CAS 109-94-4 using spark-proof or non-sparking tools (or an explosion-proof vacuum) and place the collected liquid and absorbent into a sealed, labeled chemical waste container for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear full chemical-protective clothing including self-contained breathing apparatus (SCBA) during cleanup . Ethyl formate is classified for transport (UN1190, Hazard Class 3, PG II) and requires hazardous waste disposal .

1. Ethyl formate is classified as a highly flammable liquid and vapor (H225, Danger) with a flash point of -20°C to -4°F, and its vapors are heavier than air, forming explosive mixtures with air (LEL 2.8%, UEL 16%) . It is harmful if swallowed (H302, LD50 oral rat 1850 mg/kg), harmful if inhaled (H332), and causes serious eye irritation (H319) and respiratory irritation (H335) .
2. Ethyl formate is a central nervous system depressant; inhalation may cause irritation, headache, dizziness, nausea, and unconsciousness at high concentrations . Ethyl formate CAS 109-94-4 decomposes slowly in water to form ethyl alcohol and formic acid, and thermal decomposition produces toxic and irritating fumes including carbon oxides . NIOSH REL and OSHA PEL are TWA 100 ppm (300 mg/m³); IDLH is 1500 ppm .
3. Always consult the specific Safety Data Sheet (SDS) for Ethyl formate for complete hazard information, first-aid procedures (P305+P351+P338 for eyes, P303+P361+P353 for skin, P301+P330+P331 for ingestion), and handling instructions. Precautionary statements include P210 (keep away from heat/sparks/open flames), P233 (keep container tightly closed), P240 (ground/bond container), and P280 (wear protective gloves/eye protection) .
