Description

Triethyl 2,2-Dichloro-2-Phosphonoacetate is a versatile organophosphorus compound that serves as a key synthetic intermediate in the production of more complex molecules. Its value lies in its reactive dichloroacetate and phosphonate ester functional groups, which enable its use in various coupling and derivatization reactions. This product is primarily needed by research and development laboratories, agrochemical manufacturers, and pharmaceutical companies for synthesizing novel compounds, including potential herbicides and biologically active agents.

Application

• Agrochemical Intermediate: A key building block in the synthesis of novel phosphonate-based herbicides and plant growth regulators.
• Pharmaceutical Research: Used in medicinal chemistry for the development of new drug candidates, particularly those incorporating phosphonate or α-halogenated ester motifs.
• Chemical Synthesis: Serves as a versatile reagent in organic synthesis for Horner-Wadsworth-Emmons (HWE) olefination reactions and other carbon-carbon bond forming processes.
• Ligand & Catalyst Precursor: Acts as a starting material for the preparation of specialized phosphonate ligands used in coordination chemistry and catalysis.
• Material Science: Investigated as a monomer or additive for creating functional polymers with specific properties.

Quality Control

Our Triethyl 2,2-Dichloro-2-Phosphonoacetate is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatographic purity assessment and identity confirmation, to ensure it meets high standards for research and industrial use. Certificates of Analysis (COA) documenting key specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture.
