It is classified as a flammable liquid and reproductive toxicant, requiring careful handling due to its hazardous properties including acute toxicity and reproductive effects.

What are the physicochemical properties of 2-methoxyethanol?

2-methoxyethanol is a clear, colorless liquid with a mild, pleasant odor at room temperature. It exhibits excellent solubility in water and most organic solvents due to its dual hydrophilic and lipophilic character. The compound has a relatively low molecular weight of 76.09 g/mol, contributing to its volatility and miscibility properties that make it valuable as a solvent.

What is 2-methoxyethanol used for?

2-methoxyethanol serves as a solvent in various industrial applications including paints, coatings, and printing inks. It acts as a coupling agent in cleaning formulations and is used in the production of resins and plasticizers. The compound also finds application in the electronics industry for specialized cleaning processes and as a component in certain chemical synthesis reactions.

How to handle 2-methoxyethanol safely?

2-methoxyethanol requires strict safety measures including use of chemical-resistant gloves, safety goggles, and respiratory protection in poorly ventilated areas. Work should be conducted in well-ventilated spaces or under fume hoods due to its toxic vapors. Avoid skin contact and inhalation, as the substance can be absorbed through skin and cause reproductive harm and acute toxicity.

How to store 2-methoxyethanol correctly?

2-methoxyethanol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources. Keep containers in original packaging and separate from incompatible materials such as strong oxidizers. Storage areas must comply with flammable liquid storage requirements and be equipped with appropriate fire suppression systems due to its Class 3 flammable classification.

What to do in case of contact with 2-methoxyethanol?

Immediate skin contact with 2-methoxyethanol requires thorough washing with soap and water for at least 15 minutes while removing contaminated clothing. For eye contact, flush with clean water for 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. In all cases of exposure, seek medical attention promptly due to the substance's reproductive toxicity and acute toxic effects.
