(4-Fluoro-2-methylphenyl)thiourea CAS 946612-94-8

Description

Compared with other compounds in its class, the molecular weight of 184.23 g/mol gives (4-Fluoro-2-methylphenyl)thiourea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(4-Fluoro-2-methylphenyl)thiourea (CAS 946612-94-8) is a high-purity analytical reference standard with the molecular formula C8H9FN2S and a molecular weight of 184.23 g/mol.

(4-Fluoro-2-methylphenyl)thiourea (C8H9FN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (4-Fluoro-2-methylphenyl)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.
