Chemical Structure

5-Fluoro-6-nitro-1H-indazole CAS 1360952-20-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 181.12 g/mol gives 5-Fluoro-6-nitro-1H-indazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Fluoro-6-nitro-1H-indazole (CAS 1360952-20-0), molecular formula C7H4FN3O2 and molecular weight 181.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 5-Fluoro-6-nitro-1H-indazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 181.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
