Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Chloro-4,5-bis((4-chlorobenzyl)thio)pyridazine (CAS 5589-92-4), a certified reference material (molecular formula C18H13Cl3N2S2, MW 427.80 g/mol) for analytical method development and quality control.
The molecular framework of 3-Chloro-4,5-bis((4-chlorobenzyl)thio)pyridazine (C18H13Cl3N2S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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).
As a certified reference material (CRM), 3-Chloro-4,5-bis((4-chlorobenzyl)thio)pyridazine 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.
