Description

Pentyllithium Solution CAS NO 3525-31-3 is a highly reactive organolithium compound widely used as a powerful base and nucleophile in organic synthesis. Its value lies in its ability to efficiently introduce the pentyl group into molecular frameworks, enabling the construction of complex organic molecules. This solution is essential for research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries.

Application

• As a key reagent for alkyl-lithiation reactions in the synthesis of complex organic intermediates.
• In the preparation of pentylated fine chemicals and active pharmaceutical ingredients (APIs).
• As a strong base for deprotonation and metal-halogen exchange reactions in synthetic chemistry.
• For the synthesis of specialty polymers and advanced materials requiring specific alkyl chain initiators.
• In agrochemical research for creating novel compounds with pentyl functional groups.
• As a precursor for generating other organometallic reagents used in cross-coupling reactions.

Quality Control

Our Pentyllithium Solution is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including titration for precise assay determination. A Certificate of Analysis (COA) detailing purity, concentration, and solvent composition is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area, away from heat, sparks, and open flames. Due to its highly volatile and pyrophoric nature, it must be handled exclusively under an inert atmosphere using appropriate techniques.
