Description

N,n-Dimethylphosporamidic Acid Ethyl 4-(Dimethylaminosulfonyl)Phenyl Ester is a specialized organophosphorus compound with a sulfonamide functional group, offering a unique chemical scaffold for advanced synthesis. This compound matters for its role as a key intermediate in the development of high-value, functional molecules, particularly in the agrochemical and pharmaceutical sectors. It is needed by research and development chemists, process development scientists, and manufacturers in fine chemical and active ingredient production who require precise, high-purity building blocks.

Application

• As a critical synthetic intermediate in the research and development of novel agrochemicals, including potential insecticides and herbicides.
• In the pharmaceutical industry for the synthesis of active pharmaceutical ingredients (APIs) with sulfonamide or phosphoramidate moieties.
• Utilized in academic and industrial research for studying structure-activity relationships (SAR) in medicinal and bioorganic chemistry.
• As a precursor for specialty chemicals used in material science, such as ligands or functional monomers.
• Potential use in the development of enzyme inhibitors or biochemical probes due to its phosphoramidate structure.

Quality Control

Our N,n-Dimethylphosporamidic Acid Ethyl 4-(Dimethylaminosulfonyl)Phenyl Ester is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics is provided with each shipment to guarantee it meets your research and process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store under an inert atmosphere for long-term stability. Keep away from heat, sparks, and open flame.
