1,7-Dimethylindoline-2-thione CAS 156136-68-4

Description

Compared with other compounds in its class, the molecular weight of 177.27 g/mol gives 1,7-Dimethylindoline-2-thione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,7-Dimethylindoline-2-thione (CAS 156136-68-4), molecular formula C10H11NS and molecular weight 177.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,7-Dimethylindoline-2-thione (C10H11NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 1,7-Dimethylindoline-2-thione 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.
