2-[(4-Methylbenzyl)thio]ethanol

The registry reference CAS 89040-08-4 identifies 2-[(4-Methylbenzyl)thio]ethanol, a compound with molecular formula C10H14OS. PubChem places the same identity under CID 15431839. Its atom-to-atom connectivity is written as SMILES CC1=CC=C(C=C1)CSCCO, and the corresponding InChIKey is BSJMWJZAXPXXHK-UHFFFAOYSA-N. These independently formatted references describe a single, neutral molecular graph.

The name separates the structure into a two-carbon ethanol chain and a 4-methylbenzyl fragment joined through sulfur. Starting at the alcohol end, the chain contains two methylene groups before reaching the sulfur atom. Sulfur then bonds to the benzylic carbon rather than directly to the aromatic ring. A methyl substituent occupies the para position relative to that benzylic attachment. This arrangement accounts for ten carbons, fourteen hydrogens, one oxygen, and one sulfur in the stated formula.

That benzylic sulfur connection is an important part of the identity: an aryl-sulfur bond or a different methyl position would define another structure. The sequence in CC1=CC=C(C=C1)CSCCO records both the para ring substitution and the sulfur-linked hydroxyethyl chain. PubChem CID 15431839 anchors the complete graph, while CAS 89040-08-4 provides its registry number. InChIKey BSJMWJZAXPXXHK-UHFFFAOYSA-N supplies a concise cross-database check. Reading all of these fields together keeps the entry specific to 2-[(4-methylbenzyl)thio]ethanol rather than a formula-matched sulfur isomer.
