Chemical Structure
Description
Structurally, 1,5-Dithiaspiro[5.5]undecane-9-carboxylic Acid Ethyl Ester (C12H20O2S2) contains a sulfone group, 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 260.42 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).
CATO supplies 1,5-Dithiaspiro[5.5]undecane-9-carboxylic Acid Ethyl Ester (CAS 101455-39-4), a certified reference material (molecular formula C12H20O2S2, MW 260.42 g/mol) for analytical method development and quality control.
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.
