2-(3-Chlorophenyl)-3,4-dimethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one CAS 791786-74-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 274.71 g/mol gives 2-(3-Chlorophenyl)-3,4-dimethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(3-Chlorophenyl)-3,4-dimethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one (CAS 791786-74-8), a certified reference material (molecular formula C13H11ClN4O, MW 274.71 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, 2-(3-Chlorophenyl)-3,4-dimethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 274.71 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2-(3-Chlorophenyl)-3,4-dimethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-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.
