3,4-Dichloro-5-methoxy-1H-indazole CAS 1167056-25-8

Description

Compared with other compounds in its class, the molecular weight of 217.05 g/mol gives 3,4-Dichloro-5-methoxy-1H-indazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Dichloro-5-methoxy-1H-indazole (CAS 1167056-25-8), molecular formula C8H6Cl2N2O and molecular weight 217.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-Dichloro-5-methoxy-1H-indazole (C8H6Cl2N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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), 3,4-Dichloro-5-methoxy-1H-indazole 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.
