Description

Thiophosphoric Acid S-[(1,3-Dihydro-1,3-Dioxo-2H-Isoindol-2-Yl)Methyl]O,o-Diethyl Ester is a specialized organophosphorus compound that serves as a key intermediate in the synthesis of advanced chemical products. Its value lies in its unique molecular structure, which combines a phthalimide moiety with a phosphorothioate group, enabling its use in creating compounds with specific biological or material properties. This chemical is primarily required by research institutions and industrial manufacturers in the agrochemical and pharmaceutical sectors for developing novel active ingredients and fine chemicals.

Application

• Agrochemical Intermediate: A critical building block in the research and synthesis of novel insecticides, acaricides, and fungicides, leveraging its phosphorothioate chemistry.
• Pharmaceutical Research: Used as a specialized synthon for developing potential pharmaceutical candidates, particularly in medicinal chemistry programs targeting enzyme inhibition.
• Chemical Synthesis: Serves as a versatile intermediate in organic synthesis for introducing the S-[(phthalimido)methyl] O,O-diethyl phosphorothioate group into more complex molecules.
• Material Science: Investigated for use in the development of specialty polymers or functional materials where the incorporation of sulfur and phosphorus atoms is desired.
• Bioconjugation & Probe Development: Potential utility in creating biochemical probes or affinity labels due to the reactive phosphorothioate ester and the phthalimide protecting group.
