Ethyl 8-acetyl-1,4-dioxaspiro[4.5]decane-8-carboxylate CAS 2143552-99-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 256.29 g/mol gives Ethyl 8-acetyl-1,4-dioxaspiro[4.5]decane-8-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 8-acetyl-1,4-dioxaspiro[4.5]decane-8-carboxylate (CAS 2143552-99-0), molecular formula C13H20O5 and molecular weight 256.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Ethyl 8-acetyl-1,4-dioxaspiro[4.5]decane-8-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.29 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Ethyl 8-acetyl-1,4-dioxaspiro[4.5]decane-8-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
