[Arg8]-Vasotocin acetate salt is primarily used in research settings to study its effects on various physiological processes. It is often employed in experiments involving the regulation of water balance and blood pressure due to its vasopressin-like activity. This compound is also utilized in neurobiological studies to understand its role in social behaviors, such as pair bonding and parental care, particularly in animal models. Additionally, it serves as a tool in pharmacological research to investigate receptor interactions and signaling pathways related to vasotocin and vasopressin systems. Its applications extend to developmental biology, where it helps in exploring its influence on embryonic and fetal development.
