2-(P-tolyl)ethane-1-thiol CAS 102369-64-2 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.

CATO supplies 2-(P-tolyl)ethane-1-thiol (CAS 102369-64-2), a certified reference material (molecular formula C9H12S, MW 152.26 g/mol) for analytical method development and quality control.

Structurally, 2-(P-tolyl)ethane-1-thiol (C9H12S) contains sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 152.26 g/mol, it falls into the medium-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.
