Chemical Structure

1-isopropyl-1H-imidazole-2-thiol CAS 61640-26-4 chemical structure

Description

The molecular framework of 1-isopropyl-1H-imidazole-2-thiol (C6H10N2S) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).

1-isopropyl-1H-imidazole-2-thiol (CAS 61640-26-4) is a high-purity analytical reference standard with the molecular formula C6H10N2S and a molecular weight of 142.22 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), 1-isopropyl-1H-imidazole-2-thiol 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.
