Description

D-Butorphanol Tartrate is a high-purity, synthetic opioid analgesic compound. It is a critical pharmaceutical intermediate and active pharmaceutical ingredient (API) valued for its potent analgesic and antitussive properties. This product is essential for manufacturers in the pharmaceutical industry, particularly for the development and production of specialized pain management and cough suppression medications.

Application

• Pharmaceutical API: Primary use as the active ingredient in injectable and intranasal analgesic formulations.
• Analgesic Production: Manufacture of potent pain relief medications for managing moderate to severe pain, including post-operative and migraine pain.
• Veterinary Medicine: Used in veterinary practices as a sedative and analgesic for large animals.
• Research & Development: Serves as a key reference standard and building block in pharmacological research and new drug discovery.
• Controlled Substance Synthesis: A precursor in the regulated synthesis of specific opioid-based controlled pharmaceuticals.
