Organophosphate
Organophosphates (also known as phosphate esters) are a class of organophosphorus compounds with the general structure O=P(OR). They can be considered as esters of phosphoric acid. Like most functional groups organophosphates occur in a diverse range of forms, with important examples including key biomolecules such as DNA, RNA and ATP, as well as many insecticides, herbicides, and nerve agents.
Triethylphosphite
Triethylphosphite is an organophosphorus compound with the formula P(OCHCH), often abbreviated P(OEt). This colorless liquid is used as a ligand in organometallic chemistry and as a reagent in organic synthesis
