Product Details
3-(N-Methylpentylamino)propionic Acid Hydrochloride CAS No. 625120-81-2
3-(N-Methylpentylamino)propionic acid hydrochloride (CAS No. 625120-81-2) is an organic compound that appears as a white to off-white solid. It has a melting point of 101–103°C and is hygroscopic, meaning that it readily absorbs moisture from the air.
Due to its hygroscopic nature, the compound should be stored in a tightly sealed container in a dry place at room temperature. It is primarily used as a pharmaceutical intermediate, particularly in the synthesis of ibandronate sodium, an active pharmaceutical ingredient used in the treatment of osteoporosis.
