Argipressin acetate (113-79-1 (free base) )

Vasopressin acetate is a synthetic peptide hormone that acts as a potent V1 receptor agonist, exhibiting high-affinity binding (Kd ~1.3-1.4 nM) in vascular cell models. It is widely used in cardiovascular and renal research to study vasoconstriction, blood pressure regulation, and antidiuretic mechanisms in both in vitro and in vivo experimental systems.
