Chemical Structure

7-Methyl-1H-indazole-3-carbonitrile CAS 90322-84-2 chemical structure

Description

7-Methyl-1H-indazole-3-carbonitrile (CAS 90322-84-2), molecular formula C9H7N3 and molecular weight 157.17 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H7N3, 7-Methyl-1H-indazole-3-carbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 157.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

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.
