Chemical Structure

N-(2-Ethylphenyl)thiourea CAS 22265-77-6 chemical structure

Description

As a certified reference material (CRM), N-(2-Ethylphenyl)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.

N-(2-Ethylphenyl)thiourea (CAS 22265-77-6) is a high-purity analytical reference standard with the molecular formula C9H12N2S and a molecular weight of 180.27 g/mol.

Structurally, N-(2-Ethylphenyl)thiourea (C9H12N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 180.27 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.
