Chemical Structure

1-(1-Methyl-1H-indazol-3-yl)thiourea CAS 2594436-05-0 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-(1-Methyl-1H-indazol-3-yl)thiourea (CAS 2594436-05-0) is a high-purity analytical reference standard with the molecular formula C9H10N4S and a molecular weight of 206.27 g/mol.

The molecular framework of 1-(1-Methyl-1H-indazol-3-yl)thiourea (C9H10N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
