Chemical Structure
Description
The occurrence of Dimethyl 2,2'-(1,3-dioxolane-2,2-diyl)diacetate 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.
Dimethyl 2,2'-(1,3-dioxolane-2,2-diyl)diacetate (CAS 6506-31-6), molecular formula C9H14O6 and molecular weight 218.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dimethyl 2,2'-(1,3-dioxolane-2,2-diyl)diacetate (C9H14O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 218.20 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
