Description

Tetrabutylammonium Hydroxide 30-Hydrate CAS NO 147741-30-8 is a quaternary ammonium salt in its hydrated hydroxide form, serving as a powerful, non-nucleophilic organic base and phase-transfer catalyst. Its primary value lies in its solubility in both aqueous and organic media, enabling critical reactions in non-polar solvents where traditional inorganic bases are ineffective. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, particularly for alkylations, deprotonations, and as a key reagent in analytical chemistry.

Application

• Phase-Transfer Catalysis (PTC): Facilitates reactions between reagents in immiscible liquid phases, crucial for alkylation, esterification, and ether synthesis.
• Pharmaceutical Synthesis: Used as a strong, non-metallic base in the production of active pharmaceutical ingredients (APIs), especially for sensitive molecules.
• Polymer Chemistry: Acts as a catalyst in the production of specialty polymers, including polycarbonates and epoxies.
• Analytical Chemistry: Serves as an ion-pairing agent in High-Performance Liquid Chromatography (HPLC) for the separation of acidic compounds.
• Electrolyte Component: Utilized in electrochemical applications and as a supporting electrolyte in non-aqueous systems.
• Organic Synthesis Reagent: Employed for deprotonation and generation of carbanions in various C-C bond-forming reactions.
• Surfactant & Corrosion Inhibitor Research: Investigated for its surface-active properties and potential use in formulation chemistry.

Quality Control

Our Tetrabutylammonium Hydroxide 30-Hydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and a strong base/organic solvent; ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide, which can degrade the product. Keep away from incompatible materials such as strong acids and oxidizing agents.
