Chemical Structure
Description
The molecular framework of 3,4,5,7-Tetrahydro-1H-benzo[g][1,5]dithionine (C11H14S2) is characterized by sulfur-containing functionality, an aromatic ring system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 3,4,5,7-Tetrahydro-1H-benzo[g][1,5]dithionine (CAS 22887-74-7), a certified reference material (molecular formula C11H14S2, MW 210.36 g/mol) for analytical method development and quality control.
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), 3,4,5,7-Tetrahydro-1H-benzo[g][1,5]dithionine 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.
