5-Methyl-1H-indazole-4,7-diamine CAS 61920-56-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

5-Methyl-1H-indazole-4,7-diamine (CAS 61920-56-7) is a high-purity analytical reference standard with the molecular formula C8H10N4 and a molecular weight of 162.19 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5-Methyl-1H-indazole-4,7-diamine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
