Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 205.36 g/mol gives 2-(N,N-Dimethyliminium)-4-ethyl-5-mercapto-1,3-dithiol, inner salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(N,N-Dimethyliminium)-4-ethyl-5-mercapto-1,3-dithiol, inner salt (CAS 677031-20-8), a certified reference material (molecular formula C7H11NS3, MW 205.36 g/mol) for analytical method development and quality control.
The molecular framework of 2-(N,N-Dimethyliminium)-4-ethyl-5-mercapto-1,3-dithiol, inner salt (C7H11NS3) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(N,N-Dimethyliminium)-4-ethyl-5-mercapto-1,3-dithiol, inner salt 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.
