Description

CAS: 149-73-5 | C4H10O3 | 106.121 g/mol

Trimethyl orthoformate is used as a protecting group for aldehydes in organic synthesis, as an additive in polyurethane coatings and as a dehydrating agent in the preparation of surface modified colloidal silica nanoparticles. It is also used as a chemical intermediate in the preparation of vitamin B1 and sulfa drugs. It acts as an effective solvent for thallium(III) nitrate-mediated oxidations. Furthermore. It is utilized for the synthesis of chromone from keto-hydroxy naphthol in the presence of trimethylamine.

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.
