Chemical Structure

Ethyl 7-oxo-5-thiaspiro[3.4]octane-6-carboxylate CAS 1422354-53-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Ethyl 7-oxo-5-thiaspiro[3.4]octane-6-carboxylate (CAS 1422354-53-7), molecular formula C10H14O3S and molecular weight 214.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Ethyl 7-oxo-5-thiaspiro[3.4]octane-6-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
