Chemical Structure

p-Toluenethiol CAS 106-45-6 chemical structure

Description

Owing to sulfur-containing functionality, an aromatic ring system, p-Toluenethiol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 124.20 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).

p-Toluenethiol (CAS 106-45-6) is a high-purity analytical reference standard with the molecular formula C7H8S and a molecular weight of 124.20 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.

As a certified reference material (CRM), p-Toluenethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
