Desmopressin is a synthetic analog of arginine vasopressin modified at position 1 (deaminated) and position 8 (D-arginine), conferring selective V2-receptor activity and prolonged duration, making it a standard reference in antidiuretic and hemostasis research. Its receptor selectivity supports comparative studies of vasopressin pharmacology. The product is a white lyophilized powder at >=99% HPLC purity in a sealed vial. We provide lot records, OEM packaging and global logistics for laboratory orders. Custom packaging, including customer-branded vials, labels and cartons, can be arranged for distributor and OEM programs. Quality documentation in English is provided for every batch, and re-orders benefit from streamlined processing and stable pricing agreements.
