Compared with other compounds in its class, the molecular weight of 176.25 g/mol gives 1-(4-Fluorophenyl)-2-thiourea 4-fluorophenylthiourea (4-fluorophenyl)thiourea n-(4-fluorophenyl)thiourea 459-05-2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(4-Fluorophenyl)-2-thiourea 4-fluorophenylthiourea (4-fluorophenyl)thiourea n-(4-fluorophenyl)thiourea 459-05-2 (CAS 459-05-2) is a high-purity analytical reference standard with the molecular formula C7H13FN2S and a molecular weight of 176.25 g/mol.
The molecular framework of 1-(4-Fluorophenyl)-2-thiourea 4-fluorophenylthiourea (4-fluorophenyl)thiourea n-(4-fluorophenyl)thiourea 459-05-2 (C7H13FN2S) is characterized by a nitrile group, sulfur-containing functionality, fluorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
