Chemical Structure

(5-Ethylthiophen-2-yl)methanol CAS 159058-69-2 chemical structure

Description

The occurrence of (5-Ethylthiophen-2-yl)methanol is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(5-Ethylthiophen-2-yl)methanol (CAS 159058-69-2), molecular formula C7H10OS and molecular weight 142.22 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (5-Ethylthiophen-2-yl)methanol (C7H10OS) contains sulfur-containing functionality, 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 142.22 g/mol, it falls into the low-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).

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.
