Chemical Structure

1-methyl-1H-indazole-7-carbaldehyde CAS 951030-58-3 chemical structure

Description

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.

1-methyl-1H-indazole-7-carbaldehyde (CAS 951030-58-3), molecular formula C9H16N2O and molecular weight 168.24 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H16N2O, 1-methyl-1H-indazole-7-carbaldehyde contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 168.24 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.

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.
