Chemical Structure

Methyl 5-bromo-4-nitro-1H-indazole-3-carboxylate CAS 1403767-11-2 chemical structure

Description

Methyl 5-bromo-4-nitro-1H-indazole-3-carboxylate (CAS 1403767-11-2) is a high-purity analytical reference standard with the molecular formula C9H6BrN3O4 and a molecular weight of 300.07 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Methyl 5-bromo-4-nitro-1H-indazole-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Methyl 5-bromo-4-nitro-1H-indazole-3-carboxylate 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.
