Chemical Structure
Description
As a certified reference material (CRM), 1,2-Bis(3,5-dichlorophenyl)disulfane 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.
CATO supplies 1,2-Bis(3,5-dichlorophenyl)disulfane (CAS 137897-99-5), a certified reference material (molecular formula C12H6Cl4S2, MW 356.12 g/mol) for analytical method development and quality control.
The molecular framework of 1,2-Bis(3,5-dichlorophenyl)disulfane (C12H6Cl4S2) is characterized by sulfur-containing functionality, chlorine substitution, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
