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 (1E)-1-(2-Chloro-1H-indol-3-yl)-N-(3-methyl-1H-pyrazol-5-yl)methanimine (CAS 477762-90-6), a certified reference material (molecular formula C13H11ClN4, MW 258.71 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, (1E)-1-(2-Chloro-1H-indol-3-yl)-N-(3-methyl-1H-pyrazol-5-yl)methanimine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (1E)-1-(2-Chloro-1H-indol-3-yl)-N-(3-methyl-1H-pyrazol-5-yl)methanimine 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.
