4-Ethylthioanisole CAS 31218-75-4 chemical structure

Description

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.

4-Ethylthioanisole (CAS 31218-75-4) is a high-purity analytical reference standard with the molecular formula C9H12S and a molecular weight of 152.26 g/mol.

The molecular framework of 4-Ethylthioanisole (C9H12S) is characterized by sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-Ethylthioanisole 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.
