7-Chloro-2-isopropyl-2H-pyrazolo[3,4-d]pyridazine CAS 1823876-43-2

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 7-Chloro-2-isopropyl-2H-pyrazolo[3,4-d]pyridazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.64 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).

7-Chloro-2-isopropyl-2H-pyrazolo[3,4-d]pyridazine (CAS 1823876-43-2) is a high-purity analytical reference standard with the molecular formula C8H9ClN4 and a molecular weight of 196.64 g/mol.

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), 7-Chloro-2-isopropyl-2H-pyrazolo[3,4-d]pyridazine 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.
