General Information
Desmopressin Impurities and Desmopressin
Daicel Pharma synthesizes high-quality Desmopressin impurity, N, N’-dimethyl-Gly-Desmopressin, which helps in the quality, stability, and biological safety analysis of Desmopressin. We also offer custom synthesis of Desmopressin impurities and supply worldwide.
Desmopressin [CAS: 16679-58-6], a peptide of nine amino acids, is a synthetic analog of the natural pituitary hormone, 8-arginine vasopressin, an antidiuretic hormone (ADH). It manages various medical conditions, such as von Willebrand disease, sickle cell disease, diabetes insipidus, and nocturnal enuresis.
Desmopressin: Use and Commercial Availability
Desmopressin is a drug with different forms of administration and indications. When administered intranasally, it is for adults with nocturia due to nocturnal polyuria and managing central cranial diabetes insipidus or temporary polyuria and polydipsia following head trauma or surgery in the pituitary region. When administered parenterally, it is for maintaining hemostasis during surgical procedures and postoperatively in patients with hemophilia A or mild to moderate classic von Willebrand’s disease (Type I).
The availability of Desmopressin varies depending on the country and the type of medical treatment. The common brand names under which Desmopressin is available are DDAVP, DesmoMelt, Desmotabs, Noctiva, Minirin, Octim, and Stimate.

Desmopressin Structure and Mechanism of Action
The chemical formula of Desmopressin is C46H64N14O12S2, and its molecular weight is 1069.22 g/mol.
On binding of Desmopressin to V2 receptors in the basolateral membrane of the distal tubule cells and collecting ducts of the nephron adenylyl cyclase is stimulated. The resulting intracellular cascades in the collecting duct lead to an increased insertion rate of water channels, called aquaporins, into the lumenal membrane and enhance the membrane permeability to water1.
Desmopressin Impurities and Synthesis
Desmopressin is a synthetic peptide hormone analog, synthesized2 through multiple steps, including solid-phase peptide synthesis and chromatography purification. During the manufacturing process, there is a potential for impurities to arise, such as truncated or modified peptide chains, residual solvents, and heavy metals. Strict quality control measures are taken to ensure the purity and quality of Desmopressin, including testing for impurities using HPLC and liquid chromatography-mass spectrometry (LC-MS). The synthesis and quality control of Desmopressin is critical to ensure the purity and efficacy of the medication.
At Daicel, we provide a Certificate of Analysis (CoA) from a cGMP-compliant analytical facility for Desmopressin impurity standard such as N, N’-dimethyl-Gly-Desmopressin, along with complete characterization data including 1H NMR, 13C NMR, IR, MASS, and HPLC purity. Upon request, we provide 13C-DEPT and CHN. Also, we provide a complete characterization report upon delivery. Daicel offers Desmopressin D8, which is a deuterium-labeled standard of Desmopressin in bioanalytical research and BA/BE studies with isotope data in CoA.
