Description
CATO supplies 6-(Thiophen-3-yl)-1H-indazole (CAS 281203-98-3), a certified reference material (molecular formula C11H8N2S, MW 200.26 g/mol) for analytical method development and quality control.
6-(Thiophen-3-yl)-1H-indazole (C11H8N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 6-(Thiophen-3-yl)-1H-indazole 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.
