3-Methoxypropylamine CAS 5332-73-0 MOPA

3-Methoxypropylamine (MOPA) is a widely used primary amine compound, mainly used as a mineral flotation agent, and its selectivity for iron ore flotation is higher than that of ordinary surfactants.

In addition, 3-methoxypropylamine can be used as an important intermediate for the synthesis of dyes such as dispersed turquoise blue S-GL, and can also be widely used in metal corrosion inhibitor formulations, with the formulation dosage accounting for 5-15% of the total formulation weight. Corrosion inhibitors are gradually being promoted and applied in the field of petrochemicals, giving 3-methoxypropylamine a good application prospect.
