(R)-Ethyl 2-(6-hydroxy-2,3-dihydrobenzo[b]thiophen-3-yl)acetate CAS 1022980-00-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-Ethyl 2-(6-hydroxy-2,3-dihydrobenzo[b]thiophen-3-yl)acetate.

(R)-Ethyl 2-(6-hydroxy-2,3-dihydrobenzo[b]thiophen-3-yl)acetate (CAS 1022980-00-2) is a high-purity analytical reference standard with the molecular formula C12H14O3S and a molecular weight of 238.30 g/mol.

Based on its molecular formula C12H14O3S, (R)-Ethyl 2-(6-hydroxy-2,3-dihydrobenzo[b]thiophen-3-yl)acetate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
