1-(3-Bromo-4-fluorophenyl)thiourea CAS 1263376-63-1

Description

The occurrence of 1-(3-Bromo-4-fluorophenyl)thiourea is closely related to a nitrile group, sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3-Bromo-4-fluorophenyl)thiourea (CAS 1263376-63-1), molecular formula C7H6BrFN2S and molecular weight 249.10 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(3-Bromo-4-fluorophenyl)thiourea (C7H6BrFN2S) contains a nitrile group, sulfur-containing functionality, fluorine/bromine substitution, an aromatic ring system. 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 249.10 g/mol, it falls into the medium-molecular-weight range. 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.
