Import Diethyl P-Tolunesulponyloxymethyl Phosphonate — Buy in Bulk from Supplier in China

Diethyl p-tolunesulponyloxymethyl phosphonate is an organophosphorus compound with the CAS number 13512-86-8, used primarily as an intermediate in organic synthesis. The listing confirms a purity level exceeding 98%, measured by HPLC, and it is supplied as a white to off-white crystalline solid. This material is stable under standard storage conditions and has a melting point range of 85 to 88 degrees Celsius, consistent with published literature for this compound.

The compound is synthesized through a multi-step reaction involving p-toluenesulfonyl chloride and diethyl phosphite, with purification via recrystallization. Typical industry standards for such intermediates require moisture content below 0.5% and foreign matter under 0.1%, though these are not explicitly confirmed by the supplier. The product is packaged in HDPE drums lined with polyethylene, with standard net weights of 25 kg or 50 kg per container, aligning with common chemical logistics practices.

This chemical is primarily purchased by pharmaceutical manufacturers for the synthesis of kinase inhibitors and agrochemical intermediates, particularly in the development of phosphonate-based herbicides. Buyers in Europe and North America commonly source it for R&D or pilot-scale production. Trade terms offered include FOB Shanghai and CIF ports, with payment via T/T or L/C. The supplier does not specify MOQ or lead time; buyers must confirm these directly.
