Description

Levallorphan Tartrate is a potent opioid receptor antagonist with a tartrate salt formulation, identified by CAS NO 71-82-9. This compound is critically important for its role in pharmacological research and development, particularly in the study of opioid receptor mechanisms and the development of treatments for substance use disorders. It is primarily needed by pharmaceutical R&D laboratories, analytical reference standard producers, and academic institutions conducting neuropharmacology studies.

Application

• Pharmacological Research: Used as a key reference standard and tool compound in studies investigating the function and binding of opioid receptors (mu, kappa, delta).
• Drug Discovery & Development: Serves as a starting material or intermediate in the synthesis of novel opioid antagonists and related therapeutic agents.
• Analytical Chemistry: Employed as a high-purity certified reference material (CRM) for method development, validation, and quality control in pharmaceutical analysis (HPLC, LC-MS).
• Neuroscience Studies: Applied in preclinical research to understand pain pathways, addiction mechanisms, and the effects of opioid modulation.
• Biochemical Assays: Utilized in receptor binding assays and other in vitro tests to screen for opioid activity and assess drug-receptor interactions.
