2,6-Diethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one CAS 1823934-76-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,6-Diethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one.

CATO supplies 2,6-Diethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one (CAS 1823934-76-4), a certified reference material (molecular formula C9H12N4O, MW 192.22 g/mol) for analytical method development and quality control.

The molecular framework of 2,6-Diethyl-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one (C9H12N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2,6-Diethyl-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.
