Chemical Structure

1-phenyl-2-sulfanylethan-1-ol CAS 28713-50-0 chemical structure

Description

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.

1-phenyl-2-sulfanylethan-1-ol (CAS 28713-50-0), molecular formula C8H10OS and molecular weight 154.23 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-phenyl-2-sulfanylethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 154.23 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).

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.
