Description

3-[(1E)-{[(5-chloro-1,2,3-thiadiazol-4-yl)methoxy]amino}methylidene]-1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]thiourea (CAS 477885-60-2) is a high-purity analytical reference standard with the molecular formula C11H7Cl2F3N6OS2 and a molecular weight of 431.24 g/mol.

The molecular framework of 3-[(1E)-{[(5-chloro-1,2,3-thiadiazol-4-yl)methoxy]amino}methylidene]-1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]thiourea (C11H7Cl2F3N6OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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).

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), 3-[(1E)-{[(5-chloro-1,2,3-thiadiazol-4-yl)methoxy]amino}methylidene]-1-[3-chloro-5-(trifluoromethyl)pyridin-2-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.
