Description

1,1,2,2-Tetraethoxyethane is a high-purity acetal derivative, valued for its role as a versatile protecting group reagent and a key synthetic intermediate in organic chemistry. Its primary commercial significance lies in its ability to form stable acetals and ketals under mild conditions, facilitating complex multi-step syntheses. This product is essential for research and production in the pharmaceutical, agrochemical, and fine chemical sectors, where precise molecular construction is critical.

Application

• Pharmaceutical Synthesis: As a protecting group for carbonyl compounds (aldehydes and ketones) during the multi-step synthesis of active pharmaceutical ingredients (APIs).
• Agrochemical Manufacturing: Used in the production of advanced pesticides and herbicides as a key building block or protecting agent.
• Fine Chemical Production: Serves as a crucial intermediate in the synthesis of fragrances, flavors, and specialty polymers.
• Organic Research & Development: A valuable reagent in academic and industrial R&D labs for developing new synthetic methodologies and novel compounds.
• Crosslinking Agent: Potential use in the formulation of specialty resins and polymers requiring acetal-based crosslinks.

Quality Control

Our 1,1,2,2-Tetraethoxyethane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents, acids, and heat sources. The container should be kept tightly sealed when not in use to minimize moisture absorption and prevent evaporation.
