Chemical Structure
Description
As a certified reference material (CRM), N-(5-Chloro-2-fluorophenyl)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.
N-(5-Chloro-2-fluorophenyl)hydrazinecarbothioamide (CAS 1155049-13-0), molecular formula C7H7ClFN3S and molecular weight 219.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(5-Chloro-2-fluorophenyl)hydrazinecarbothioamide (C7H7ClFN3S) is characterized by a nitrile group, sulfur-containing functionality, fluorine/chlorine 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 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.
