Description

tert-Butoxy CAS NO 3141-58-0 is a highly reactive alkoxide compound, widely utilized as a versatile reagent and intermediate in advanced chemical synthesis. Its primary value lies in its strong nucleophilic and basic properties, making it essential for deprotonation reactions and the formation of ethers and esters. This chemical is particularly critical for research and development laboratories, pharmaceutical manufacturing, and specialty chemical producers who require high-purity building blocks for complex molecule construction.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for creating tert-butyl ether protecting groups.
• Polymerization Catalyst/Initiator: Used as an initiator or co-catalyst in the production of specialized polymers and elastomers.
• Organic Synthesis Reagent: Employed as a strong base for deprotonation and as a nucleophile in Williamson ether synthesis and similar coupling reactions.
• Fine Chemical Production: Serves as a precursor in the manufacture of agrochemicals, flavors, fragrances, and other high-value fine chemicals.
• Laboratory Research: A valuable reagent in academic and industrial R&D for methodological development and exploratory chemistry.
• Surface Modification Agent: Used in material science to modify surface properties of inorganic or polymeric materials.

Quality Control

Our tert-Butoxy is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and impurity profile analysis, to ensure it meets the high-purity standards required for sensitive synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and specific impurity levels are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties as a strong base and its sensitivity to moisture and carbon dioxide, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids and oxidizing agents.
