Chemical Structure

4-Ethoxybenzenethiol CAS 699-09-2 chemical structure

Description

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Ethoxybenzenethiol 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).

4-Ethoxybenzenethiol (CAS 699-09-2) is a high-purity analytical reference standard with the molecular formula C8H10OS and a molecular weight of 154.23 g/mol.

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.

CATO manufactures 4-Ethoxybenzenethiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
