Chemical Structure
Description
CATO supplies 1-(3-Hydroxybenzo[b]thiophen-2-yl)ethan-1-one (CAS 3260-92-2), a certified reference material (molecular formula C10H8O2S, MW 192.23 g/mol) for analytical method development and quality control.
Structurally, 1-(3-Hydroxybenzo[b]thiophen-2-yl)ethan-1-one (C10H8O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 192.23 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).
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.
