Description
Vasopressin Product Overview
Vasopressin, also known as antidiuretic hormone (ADH), is a cyclic nonapeptide with a disulfide bridge between two cysteine residues. The form used in human medicines is argipressin (C46H65N15O12S2, CAS 113-79-1), which carries arginine at position 8. It is supplied as a white, lyophilized powder that is soluble in water.
Pharmaceutical companies use vasopressin to formulate injectable products used in hospital settings. It is the parent molecule of synthetic analogues such as Desmopressin and Terlipressin, and it is structurally related to Oxytocin Acetate, which differs in only two amino acids.
As a peptide, it is sensitive to heat and moisture and is shipped and stored under cold conditions. Zyntex supplies it from qualified peptide API producers and provides lot-specific documentation before ordering. The API is supplied only to licensed pharmaceutical companies.
