Ethyl 2-(6-methoxy-2,3-dihydrobenzo[b]thiophen-3-yl)acetate CAS 905724-73-4

Description

Compared with other compounds in its class, the molecular weight of 252.33 g/mol gives Ethyl 2-(6-methoxy-2,3-dihydrobenzo[b]thiophen-3-yl)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-(6-methoxy-2,3-dihydrobenzo[b]thiophen-3-yl)acetate (CAS 905724-73-4) is a high-purity analytical reference standard with the molecular formula C13H16O3S and a molecular weight of 252.33 g/mol.

Structurally, Ethyl 2-(6-methoxy-2,3-dihydrobenzo[b]thiophen-3-yl)acetate (C13H16O3S) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 252.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
