Methoxypropylamine (MOPA) is a clear liquid that undergoes the usual reactions of primary amines and is completely soluble in water and organic solvents. The application of this compound is as flocculants in water treatment systems and as a solvent in the paint and textile industries.
Physical and Chemical Properties:
3-methoxypropylamine (MOPA) is a clear, colorless to faintly colored liquid. It typically and an ammonia-like odor. It has properties typical of primary amines and is miscible with water, ethanol, toluene, acetone, hexane, and other standard solvents. In addition, methoxypropylamine does not have a distinct odor in dilute solutions. The most important physical and chemical properties of this compound can be summarized in the following table:

|Chemical Structure Depiction|
The reaction of 3-methoxypropylamine with base disulfides (2-carbamoylphenyl) results in the production of products useful in the control of mold fungi in latex and alkyd paints.
By the reaction of 3 Methoxypropylamine and sodium hydroxide, a new useful material for paint removal is obtained. (phenol-free paint removers)
- This compound finds abundant use in insecticide emulsions, textiles, and paint solvents.
- It has been used in the production of polybutadiene-based isocyanates and polyamide resins.
- Modification of aluminum surfaces and their alloys has been done with dilute solutions of this material and it has been reported that this material improves the adhesion of coatings that are applied later.
- MOPA is used in the production of amine soaps and fatty acids and some natural resins and products that are used in paint and other industries.
- In making waxes that are insensitive to water MOPA is used
- In washing powders and to improve their function in low temperatures
- This material is used as an additive to prevent corrosion of oil refining equipment. The presence of acidic substances in the input crude oil causes corrosion in the condensate.
- This material does not have a recognizable odor in solutions, and in comparison with morphine, it might be an awesome substitute.
- It is also used in plant growth regulators.
- Causes severe skin burns and eye damage.
- Harmful if swallowed.
- Flammable liquid and vapor.
- Exposure to high concentrations of vapor in this compound can irritate the respiratory tract or cause blurred vision.
- May cause an allergic skin reaction.
- Harmful to aquatic life with long-lasting effects.
