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. Samples for quality evaluation can be arranged for serious buyers, with sample cost credited against the first bulk order in most cases. Our pricing structure supports both small laboratory orders and large wholesale contracts, and payment options include major transfer and trade platforms.
