About HS Code 293143

This HS code specifies diethyl ethylphosphonate, another non-halogenated organo-phosphorous derivative. This versatile compound serves as a crucial chemical intermediate in the synthesis of pharmaceuticals, agrochemicals, and as a solvent or flame retardant additive in various industrial applications. It is primarily traded by specialty chemical producers and companies within the pharmaceutical and polymer industries. Its unique properties, including its solvency and reactivity, make it a valuable component in diverse synthetic pathways and material formulations.

Products Under This Code

Diethyl ethylphosphonate, DEEP, Ethylphosphonic acid diethyl ester, Diethyl ethylphosphonate (DEEP)

Real World Examples
