It has good solubility in water and is miscible with most organic solvents including alcohols and ethers. The compound has a relatively low volatility and moderate viscosity. Its ester structure makes it biodegradable, and it exhibits typical ester reactivity including hydrolysis under acidic or basic conditions.

Ethyl 2-hydroxypropanoate serves as an environmentally friendly solvent in various industrial applications including paints, coatings, and cleaning formulations. It is widely used in the pharmaceutical industry as a solvent for drug synthesis and formulation. The food industry employs it as a flavoring agent due to its pleasant fruity aroma. Additionally, it finds applications in cosmetics, personal care products, and as a green alternative to traditional petroleum-based solvents.

Ethyl 2-hydroxypropanoate requires careful handling due to its flammable nature and potential for eye damage. Always wear appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation. Keep away from ignition sources, heat, and open flames. Avoid direct contact with eyes and skin. Use explosion-proof electrical equipment in areas where vapors may be present.

Ethyl 2-hydroxypropanoate should be stored in a cool, dry, well-ventilated area away from heat sources and ignition points. Use appropriate containers made of compatible materials and ensure they are tightly sealed to prevent vapor escape. Store separately from strong oxidizing agents and incompatible materials. Maintain storage temperatures below 25°C when possible and protect from direct sunlight. Implement proper fire prevention measures in storage areas.

Ethyl 2-hydroxypropanoate contact requires immediate action, especially for eyes due to its corrosive classification. For eye contact, immediately flush with plenty of water for at least 15 minutes and seek medical attention urgently. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek medical advice. Remove contaminated clothing and wash before reuse.

Ethyl 2-hydroxypropanoate disposal must comply with local and national waste regulations as it is classified as hazardous waste. Do not pour down drains or dispose of with regular waste. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities may be suitable for incineration at appropriate facilities. Consider recycling or recovery options where available. Always consult local environmental authorities for specific disposal requirements in your region.

Ethyl 2-hydroxypropanoate is classified under ADR Class 3 (flammable liquids), Packing Group III for transportation purposes. It requires appropriate UN-specification packaging and hazard labeling including flammable liquid markings. Transport vehicles must comply with ADR regulations for Class 3 substances. Ensure proper documentation including transport documents and safety data sheets. Drivers must have appropriate training and certification for transporting hazardous materials.
