3-[(1E)-(Dimethylamino)methylidene]-1-phenylthiourea CAS 1661847-00-2

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.

3-[(1E)-(Dimethylamino)methylidene]-1-phenylthiourea (CAS 1661847-00-2) is a high-purity analytical reference standard with the molecular formula C10H13N3S and a molecular weight of 207.30 g/mol.

The molecular framework of 3-[(1E)-(Dimethylamino)methylidene]-1-phenylthiourea (C10H13N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
