Pyrazolo[1,5-b]pyridazine-3-carboxaldehyde CAS 87754-35-6

Description

The occurrence of Pyrazolo[1,5-b]pyridazine-3-carboxaldehyde is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Pyrazolo[1,5-b]pyridazine-3-carboxaldehyde (CAS 87754-35-6) is a high-purity analytical reference standard with the molecular formula C7H5N3O and a molecular weight of 147.13 g/mol.

The molecular framework of Pyrazolo[1,5-b]pyridazine-3-carboxaldehyde (C7H5N3O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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), Pyrazolo[1,5-b]pyridazine-3-carboxaldehyde 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.
