Description

CAS: 3699-66-9 | C9H19O5P | 238.22 g/mol

Triethyl 2-phosphonopropionate is used as a reactant in intramolecular conjugate addition for the synthesis of floresolide B, enantioselective synthesis of spiroindane di-methyl acetic acid and in stereo selective intramolecular Diels-Alder reactions. It plays an important role in Horner-Wadsworth-Emmons reactions and chemoenzymatic one-pot synthesis of gamma-butyrolactones. It is also used in the preparation of 3-[2]furyl-2-methyl-acrylic acid ethyl ester by reacting with furfural.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
