Cinchonidine (CAS 485-71-2) is a cinchona alkaloid isolated from the bark of Cinchona species, structurally similar to quinine but with opposite configuration at C8 and C9. It is supplied as a white to off-white crystalline powder with ≥98% purity by HPLC, and is widely used as a chiral ligand in asymmetric synthesis and as a pharmaceutical intermediate.
This product is ideal for R&D and commercial-scale applications requiring a reliable source of natural cinchona alkaloid. Each batch is tested for assay, specific rotation, and residual solvents, ensuring consistent quality for demanding syntheses.
Synonyms: (8α,9R)-Cinchonan-9-ol, Cinchonidine base, (R)-(6-Methoxy-4-quinolyl)-5-vinylquinuclidine-2-methanol, 9-epi-Cinchonine
Every batch is tested for assay (HPLC ≥98%), specific rotation, loss on drying (≤0.5%), and heavy metals (≤10 ppm). Full COA, MSDS, and TDS are available on request; stability data can be provided for qualification.
Standard packaging: 1 kg, 5 kg, 25 kg; bulk and custom packing available. In-stock items ship within 3-5 days; MOQ from 1 kg. For pricing, samples, and bulk orders, contact our sales team.
