Chemical Structure

4,5,6,7-Tetrahydro-1H-indazole CAS 2305-79-5 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.

4,5,6,7-Tetrahydro-1H-indazole (CAS 2305-79-5) is a high-purity analytical reference standard with the molecular formula C7H10N2 and a molecular weight of 122.17 g/mol.

The molecular framework of 4,5,6,7-Tetrahydro-1H-indazole (C7H10N2) is characterized by a nitrile group, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
