Chemical Structure
Description
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.
1-(4-Chloro-5-fluoro-2-iodophenyl)-1H-tetrazole (CAS 1430115-38-0), molecular formula C7H3ClFIN4 and molecular weight 324.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(4-Chloro-5-fluoro-2-iodophenyl)-1H-tetrazole (C7H3ClFIN4) is characterized by a nitrile group, fluorine/chlorine/iodine 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).
As a certified reference material (CRM), 1-(4-Chloro-5-fluoro-2-iodophenyl)-1H-tetrazole 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.
