78-90-0 1,2-Diaminopropane
PRODUCT INTRODUCTION
1,2-propylenediamine appears as a colorless liquid with an ammonia-like odor. Strongly irritates skin and tissue. Propylenediamine is a diamine that is propane substituted by amino groups at positions 1 and 2. Propylenediamine is commonly used as a bidentate ligand in the formation of coordination complexes. It has a role as a ligand. In conjunction with cupric sulfate it is a very sensitive reagent for mercury.
