2,2-Dimethoxypropane

2,2-Dimethoxypropane (CAS 77-76-9), also known as 2,2-DMP, acetone dimethyl ketal, or NSC 62085, is a short-chain acetal solvent with the molecular formula C5H12O2. It carries no assigned E-code and is classified under HS code 29110000 within the broader acetal and hemiacetal chemical family.

In pharmaceutical and biotech manufacturing, 2,2-DMP functions as a dehydrating agent and protecting-group reagent, reacting with diols to form cyclic acetals under mild acid catalysis and driving reactions by consuming trace water. In food applications it acts as a flavorant and antimicrobial carrier, delivering controlled release of acetone and methanol upon hydrolysis under acidic conditions.

2,2-DMP is sourced in solvent-grade and food-grade qualities, with supply compliant to REACH registration requirements for the European market. FCC-grade material is available for food and flavour applications. Standard packaging includes drums and IBCs, with documentation available to support pharmaceutical and food-grade qualification processes.
