Ammonium sulfate, ≥99.0%, AR-15N2（Cat No.:I041445）is a high-purity form of ammonium sulfate where nitrogen atoms are isotopically labeled with nitrogen-15 (15N), a stable isotope. This compound is used in various analytical and research applications, particularly in isotopic labeling experiments and NMR spectroscopy, where the presence of 15N enables precise tracking of nitrogen-containing compounds. Ammonium sulfate is widely used in protein purification, especially in salting out proteins, as well as in fertilizer production. The 15N labeling enhances studies on nitrogen metabolism, chemical reactions, and molecular dynamics in organic and biological research.
