5-Chloro-2-ethyl-6-phenyl-2,3-dihydropyridazin-3-one CAS 861208-89-1

Description

The occurrence of 5-Chloro-2-ethyl-6-phenyl-2,3-dihydropyridazin-3-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Chloro-2-ethyl-6-phenyl-2,3-dihydropyridazin-3-one (CAS 861208-89-1), a certified reference material (molecular formula C12H11ClN2O, MW 234.68 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-Chloro-2-ethyl-6-phenyl-2,3-dihydropyridazin-3-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.68 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).

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), 5-Chloro-2-ethyl-6-phenyl-2,3-dihydropyridazin-3-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.
