Chemical Structure

(1H-Indol-7-yl)thiourea CAS 866017-50-7 chemical structure

Description

As a certified reference material (CRM), (1H-Indol-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.

(1H-Indol-7-yl)thiourea (CAS 866017-50-7) is a high-purity analytical reference standard with the molecular formula C9H9N3S and a molecular weight of 191.25 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, (1H-Indol-7-yl)thiourea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 191.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
