1-(4-(Tert-butyl)phenyl)ethane-1-thiol CAS 138947-78-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 1-(4-(Tert-butyl)phenyl)ethane-1-thiol (CAS 138947-78-1), a certified reference material (molecular formula C12H18S, MW 194.34 g/mol) for analytical method development and quality control.

The molecular framework of 1-(4-(Tert-butyl)phenyl)ethane-1-thiol (C12H18S) is characterized by sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
