Regulatory Information
Chemical: Propanoic acid, 3-ethoxy-, ethyl ester
Propanoic acid, 3-ethoxy-, ethyl ester is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Propanoic acid, 3-ethoxy-, ethyl ester are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

Fire HazardsExcerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]:
Health HazardsLiquid or mist may irritate th eyes and skin. May cause headache, nausea and vomiting, central nervous system depression with dizziness, drowsiness and unconsciousness. (USCG, 1999)
Hazards Summary
It appears to be similar to other esters with low toxicity. It is a mild mucous membrane irritant. Animal studies show no adverse effects below 250 ppm. Its unpleasant odor limits use as a substitute for glycol ethers in the electronics industry. [Sullivan, p. 450-1] A skin and eye irritant; Inhalation of high concentrations can cause CNS depression; [CAMEO]
Reactive GroupEsters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
EPA Safer ChemicalChemical: Ethyl-3-ethoxy propionate
Reactivity Profile
ETHYL-3-ETHOXYPROPIONATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Air and Water ReactionsNo rapid reaction with air. No rapid reaction with water.
