Chemical Structure
Description
As a certified reference material (CRM), 1-(4-(6-(o-Tolyl)pyridazin-3-yl)piperazin-1-yl)butan-1-one 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.
1-(4-(6-(o-Tolyl)pyridazin-3-yl)piperazin-1-yl)butan-1-one (CAS 1021256-53-0), molecular formula C19H24N4O and molecular weight 324.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-(4-(6-(o-Tolyl)pyridazin-3-yl)piperazin-1-yl)butan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
