Description

Felypressin CAS NO 56-59-7 is a synthetic polypeptide analog of vasopressin, known for its potent vasoconstrictive properties. This compound is a critical active pharmaceutical ingredient (API) valued for its ability to control local bleeding and prolong the action of co-administered anesthetics. It is primarily required by manufacturers in the pharmaceutical and biotechnology sectors for the formulation of hemostatic agents and specialized dental or surgical anesthetics. Our supply ensures high purity and batch-to-batch consistency for reliable integration into final drug products.

Application

• Hemostatic Agent Formulation: Key ingredient in topical and injectable solutions designed to control capillary bleeding during surgical and dental procedures.
• Local Anesthetic Adjuvant: Used in combination with local anesthetics like prilocaine to induce vasoconstriction, thereby prolonging anesthetic effect and reducing systemic absorption.
• Pharmaceutical Intermediates: Serves as a crucial building block in the synthesis of more complex peptide-based therapeutics.
• Research & Development: Utilized in biochemical and pharmacological research to study vasopressin receptor (V1) activity and related physiological pathways.
• Veterinary Medicine: Applied in veterinary surgical practices for its effective local vasoconstrictive action.

Quality Control

Our Felypressin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, peptide mapping for identity confirmation, and stringent tests for residual solvents and related substances. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, ensuring compliance with cGMP guidelines for pharmaceutical ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as specified on the label. This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment. For long-term storage, consider desiccants or inert atmosphere to maintain stability.
