Isobutyric anhydride, 97%
CAS: 97-72-3 | C8H14O3 | 158.197 g/mol
Supplier: Thermo Scientific Chemicals L13240AE
Description
Isobutyric anhydride is used in the preparation of 4-O-isobutyryl derivative by reacting with octyl beta-D-glucopyranoside using C2-symmetric chiral 4-pyrrolidinopyridine as a catalyst. It acts as a starting material for esters like sucrose acetate isobutyrate, dyes and agrochemicals. It finds application as fragrance intermediate and flavorings.
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.
