Demethyl Tetrandrine

Demethyl tetrandrine is a bisbenzylisoquinoline alkaloid structurally related to tetrandrine, differing by a single methyl group. It is isolated from the roots of Stephania tetrandra and purified to ≥98% HPLC purity. This compound has drawn attention in pharmaceutical R&D for its potential anti-inflammatory and anti-fibrotic activity, and it serves as a useful reference standard for analytical method development.

We supply demethyl tetrandrine as a white to off-white crystalline powder, packaged under inert atmosphere to ensure stability. Each batch is accompanied by a certificate of analysis, and technical documentation is available for qualification.

Synonyms: Demethyltetrandrine, Nor-tetrandrine, NSC 77037, O-Demethyltetrandrine, (1β)-1-O-Demethyltetrandrine
