2,2-Dimethyl-1,3-propanediol, 99%
CAS: 126-30-7 | C5H12O2 | 104.15 g/mol
Supplier: Thermo Scientific Chemicals A1034036
Description
Used for protection of carbonyl groups as 4,4-dimethyl-1,3-dioxanes, often preferred to the more usual 1,3-dioxolanes due to easier separation and greater stability, for protection of carbonyl group of 4-bromo-2-propanone using p-toluenesulfonic acid in the presence of triethyl orthoformate. It is used in the synthesis of polyesters, paints, lubricants, and plasticizers.
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.
