Chemical Structure

4-Ethylbenzenethiol CAS 4946-13-8 chemical structure

Description

Owing to sulfur-containing functionality, an aromatic ring system, 4-Ethylbenzenethiol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 4-Ethylbenzenethiol (CAS 4946-13-8), a certified reference material (molecular formula C8H10S, MW 138.23 g/mol) for analytical method development and quality control.

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

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.
