S-(3-Chloro-4-methylphenyl) ethanethioate CAS 1379334-64-1

Description

S-(3-Chloro-4-methylphenyl) ethanethioate (CAS 1379334-64-1), molecular formula C9H9ClOS and molecular weight 200.69 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H9ClOS, S-(3-Chloro-4-methylphenyl) ethanethioate contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), S-(3-Chloro-4-methylphenyl) ethanethioate 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.
