Description

Compared with other compounds in its class, the molecular weight of 192.28 g/mol gives (1R)-1-(3-methyl-1-benzothiophen-2-yl)ethan-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1R)-1-(3-methyl-1-benzothiophen-2-yl)ethan-1-ol (CAS 1344954-15-9), molecular formula C11H12OS and molecular weight 192.28 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (1R)-1-(3-methyl-1-benzothiophen-2-yl)ethan-1-ol (C11H12OS) contains sulfur-containing functionality, 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 192.28 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.
