2,2-Dimethoxyacetaldehyde (60% aqueous) is a key reagent in organic synthesis, widely used as a precursor in the preparation of pharmaceuticals, agrochemicals, and fine chemicals. It is a mono-protected form of glyoxal (glyoxal 1,1-dimethyl acetal), with one free aldehyde group and one aldehyde masked as a dimethyl acetal, which allows selective reaction at the free aldehyde, for example in reductive aminations and olefinations. This solution contains 60% active ingredient in water, with a CAS number of 51673-84-8, molecular formula (CH3O)2CHCHO, and a molecular weight of 104.10 g/mol. Store at ambient conditions. The product carries a signal word of "Warning" per GHS classification. Molekula supplies 2,2-Dimethoxyacetaldehyde, 60% aqueous from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
