Description

Oxytocin, (4-Ethyl-Phe)(2)- is a synthetic analogue of the neuropeptide hormone oxytocin, featuring a specific modification at the second amino acid position. This structural alteration is designed to enhance its stability and receptor-binding profile for advanced research and development applications. It is a critical compound for pharmaceutical researchers and developers working on neuroendocrine pathways, peptide therapeutics, and central nervous system disorders.

Application

• Pharmaceutical Research & Development: As a key reference standard and active ingredient in the development of novel neuropeptide-based therapeutics targeting social behavior, stress response, and reproductive functions.
• Neuroscience Studies: For in vitro and in vivo investigations into oxytocin receptor (OXTR) signaling, ligand-receptor interactions, and the modulation of neural circuits.
• Biochemical Assay Development: Used in the calibration and validation of high-throughput screening (HTS) assays, ELISA kits, and other diagnostic platforms focused on the oxytocin pathway.
• Peptide Chemistry & Analog Synthesis: Serves as a crucial intermediate or template for the synthesis of more complex or targeted peptide analogues with improved pharmacokinetic properties.
• Academic & Clinical Research: Supports fundamental research in psychology, endocrinology, and psychiatry exploring the role of oxytocin in bonding, trust, and anxiety-related disorders.

Quality Control

Our Oxytocin, (4-Ethyl-Phe)(2)- is manufactured under strict quality systems suitable for research and development. Each batch undergoes comprehensive analytical testing, including HPLC for purity and mass spectrometry for identity confirmation. A detailed Certificate of Analysis (COA) providing batch-specific results is available upon request to support your regulatory and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. The product is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation. For long-term storage, consider under an inert atmosphere.
