Manganese(II) 2-aminoacetate is primarily used in agricultural applications as a micronutrient fertilizer. It provides essential manganese to plants, which is crucial for photosynthesis, nitrogen metabolism, and enzyme activation. This compound is particularly effective in correcting manganese deficiencies in crops, improving overall plant health and yield. It is also utilized in animal feed supplements to ensure proper growth and development by supporting metabolic processes. Additionally, it finds use in certain industrial processes as a catalyst or stabilizer in chemical reactions.
