Desmopressin is a synthetic analogue of vasopressin with modifications that enhance its antidiuretic selectivity, studied in renal and neuroendocrine research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. Desmopressin is investigated in research on water balance and vasopressin-receptor signaling, and is commonly applied in cell-based and preclinical studies. The lyophilized presentation supports convenient reconstitution and reproducible dosing. We maintain strict quality control across batches and provide COA for specific batches on request. The unopened product should be stored sealed at 2-8 degree C, protected from light and moisture; for long-term storage keep at -20 degree C and avoid repeated thawing. Small and large orders are accepted, and OEM, private-label and discreet neutral-packaging services are available with worldwide delivery.
