Chemical Structure
Description
CATO supplies Dimethyl 1,3-Dithiole-2-thione-4,5-dicarboxylate (CAS 7396-41-0), a certified reference material (molecular formula C7H6O4S3, MW 250.32 g/mol) for analytical method development and quality control.
The molecular framework of Dimethyl 1,3-Dithiole-2-thione-4,5-dicarboxylate (C7H6O4S3) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Dimethyl 1,3-Dithiole-2-thione-4,5-dicarboxylate 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.
