Chemical Structure
Description
The occurrence of 6-((3-Fluorobenzyl)thio)-3-(pyridin-3-yl)-[1,2,4]triazolo[4,3-b]pyridazine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-((3-Fluorobenzyl)thio)-3-(pyridin-3-yl)-[1,2,4]triazolo[4,3-b]pyridazine (CAS 868969-08-8), molecular formula C17H12FN5S and molecular weight 337.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-((3-Fluorobenzyl)thio)-3-(pyridin-3-yl)-[1,2,4]triazolo[4,3-b]pyridazine (C17H12FN5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. 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), 6-((3-Fluorobenzyl)thio)-3-(pyridin-3-yl)-[1,2,4]triazolo[4,3-b]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.
