Chemical Structure
Description
As a certified reference material (CRM), 1-(5-Chloro-1H-indazol-3-yl)ethanone 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-(5-Chloro-1H-indazol-3-yl)ethanone (CAS 932698-80-1), a certified reference material (molecular formula C9H7ClN2O, MW 194.62 g/mol) for analytical method development and quality control.
1-(5-Chloro-1H-indazol-3-yl)ethanone (C9H7ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
