Description

Compared with other compounds in its class, the molecular weight of 330.12 g/mol gives 4-(4-Bromo-2-trifluoromethoxyphenyl)-thiosemicarbazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(4-Bromo-2-trifluoromethoxyphenyl)-thiosemicarbazide (CAS 1228245-60-0), molecular formula C8H7BrF3N3OS and molecular weight 330.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(4-Bromo-2-trifluoromethoxyphenyl)-thiosemicarbazide (C8H7BrF3N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine 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.

As a certified reference material (CRM), 4-(4-Bromo-2-trifluoromethoxyphenyl)-thiosemicarbazide 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.
