Description

(-)-Sparteine CAS NO 90-39-1 is a chiral, lupin alkaloid widely recognized as a versatile ligand and base in asymmetric synthesis. Its primary value lies in its ability to facilitate highly enantioselective transformations, which is critical for producing single-isomer pharmaceutical intermediates and fine chemicals. This product is essential for research and development laboratories, pharmaceutical manufacturers, and advanced chemical synthesis facilities focused on creating high-value chiral compounds.

Application

• As a chiral ligand in asymmetric deprotonation and alkylation reactions.
• Utilized as a base in enantioselective synthesis for pharmaceutical active ingredients (APIs).
• Employed in the resolution of racemic mixtures via diastereomeric salt formation.
• Acts as a catalyst or co-catalyst in organometallic chemistry and polymerization processes.
• Used in academic and industrial research for developing new synthetic methodologies.
• Serves as a starting material or intermediate for the synthesis of other complex alkaloids and bioactive molecules.

Quality Control

Our (-)-Sparteine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing identity, purity, and specific impurity profiles is provided with every shipment to guarantee reproducible performance in your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture ingress.
