Chemical Structure
Description
The occurrence of 2,5-Dihydro-2,5-dimethoxy-2-dimethoxymethylfuran is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,5-Dihydro-2,5-dimethoxy-2-dimethoxymethylfuran (CAS 59906-91-1), molecular formula C9H16O5 and molecular weight 204.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,5-Dihydro-2,5-dimethoxy-2-dimethoxymethylfuran is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
