Chemical Structure
Description
N-(4-bromophenyl)hydrazinecarbothioamide (CAS 2646-31-3) is a high-purity analytical reference standard with the molecular formula C7H8BrN3S and a molecular weight of 246.13 g/mol.
The molecular framework of N-(4-bromophenyl)hydrazinecarbothioamide (C7H8BrN3S) is characterized by a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), N-(4-bromophenyl)hydrazinecarbothioamide 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.
