Chemical Structure
Description
The occurrence of 1-(3-Methyl-1-benzothiophen-2-yl)ethan-1-ol is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(3-Methyl-1-benzothiophen-2-yl)ethan-1-ol (CAS 69994-68-9), molecular formula C11H12OS and molecular weight 192.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1-(3-Methyl-1-benzothiophen-2-yl)ethan-1-ol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 192.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
