Chemical Structure

1-(2H-indazol-7-yl)thiourea CAS 381211-75-2 chemical structure

Description

CATO supplies 1-(2H-indazol-7-yl)thiourea (CAS 381211-75-2), a certified reference material (molecular formula C8H8N4S, MW 192.24 g/mol) for analytical method development and quality control.

Structurally, 1-(2H-indazol-7-yl)thiourea (C8H8N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 192.24 g/mol, it falls into the medium-molecular-weight range. 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).

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.

As a certified reference material (CRM), 1-(2H-indazol-7-yl)thiourea meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
