Nalmefene HCl

Nalmefene HCl is an opioid receptor antagonist with a longer duration of action compared to Naloxone. It is primarily used in the treatment of alcohol dependence and has been studied for its ability to block the effects of various opioid receptor agonists. In neuroscience, Nalmefene is relevant for exploring the role of opioid signaling in addiction, reward pathways, and neurobehavioral disorders.

Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.

• Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
• Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
• Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
• QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
• Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity

To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
