Chemical Structure

1-(3-(Methylthio)phenyl)ethanone CAS 1441-99-2 chemical structure

Description

1-(3-(Methylthio)phenyl)ethanone (CAS 1441-99-2) is a high-purity analytical reference standard with the molecular formula C9H10OS and a molecular weight of 166.24 g/mol.

Structurally, 1-(3-(Methylthio)phenyl)ethanone (C9H10OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 166.24 g/mol, it falls into the medium-molecular-weight range. 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).

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), 1-(3-(Methylthio)phenyl)ethanone 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.
