Description

Argipressin (4-9) is a synthetic peptide fragment of the neurohypophysial hormone arginine vasopressin. This compound is a critical intermediate and research tool for studying the structure-activity relationships of vasopressin and its receptor interactions. It is primarily utilized by pharmaceutical R&D laboratories and fine chemical manufacturers engaged in peptide synthesis and neuroendocrine research. The product is supplied with a high level of purity to ensure reliable and reproducible experimental results.

Application

• Pharmaceutical Research & Development: Serves as a key intermediate in the synthesis of vasopressin analogs and related peptide therapeutics.
• Biochemical Research: Used as a reference standard and probe in receptor binding assays and studies of neurohypophysial hormone function.
• Peptide Chemistry: Acts as a building block for the solid-phase or solution-phase synthesis of longer, modified peptide sequences.
• Academic Research: Employed in university and institutional labs for investigating the physiological roles and metabolic pathways of vasopressin fragments.
• Diagnostic Development: Potential use in the development of immunoassays and diagnostic kits targeting vasopressin pathways.
