Chemical Structure
Description
The occurrence of Ethyl 5-isopropyl-1,6-dioxaspiro[2.5]octane-2-carboxylate 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.
Ethyl 5-isopropyl-1,6-dioxaspiro[2.5]octane-2-carboxylate (CAS 64322-18-5), molecular formula C12H20O4 and molecular weight 228.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 5-isopropyl-1,6-dioxaspiro[2.5]octane-2-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
