Description

Compared with other compounds in its class, the molecular weight of 167.14 g/mol gives 4-Amino-6-fluoro-1,2-dihydro-3H-indazol-3-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Amino-6-fluoro-1,2-dihydro-3H-indazol-3-one (CAS 885520-21-8), molecular formula C7H6FN3O and molecular weight 167.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Amino-6-fluoro-1,2-dihydro-3H-indazol-3-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.14 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.
