Aplicaciones

Dibenzyl phosphite is used for the phosphorylation of phenols involves reaction in the presence of N-ethyldiisopropylamine and DMAP to give the dibenzyl phenyl phosphate. It is used in the preparation of phenylalkylphosphonamidates which are then used as probes for a hydrophobic binding register in prostate-specific membrane antigen.

Notas

Store at 4°C. Moisture Sensitive. Incompatible with moisture and oxidizing agents. Store under dry inert gas. Store away from oxidizing agents.
