Chemical Structure
Description
The occurrence of Ethyl 5-ethyl-5-methyl-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.
CATO supplies Ethyl 5-ethyl-5-methyl-1,6-dioxaspiro[2.5]octane-2-carboxylate (CAS 37487-96-0), a certified reference material (molecular formula C12H20O4, MW 228.28 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 5-ethyl-5-methyl-1,6-dioxaspiro[2.5]octane-2-carboxylate (C12H20O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
