Chemical Structure

3H-[1,2]Dithiolo[3,4-b]pyridine-3-thione CAS 3445-78-1 chemical structure

Description

As a certified reference material (CRM), 3H-[1,2]Dithiolo[3,4-b]pyridine-3-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.

3H-[1,2]Dithiolo[3,4-b]pyridine-3-thione (CAS 3445-78-1), molecular formula C6H9NS3 and molecular weight 191.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3H-[1,2]Dithiolo[3,4-b]pyridine-3-thione (C6H9NS3) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 191.34 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.
