Chemical Structure
Description
As a certified reference material (CRM), 5-(3-Fluorophenyl)-2H-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.
CATO supplies 5-(3-Fluorophenyl)-2H-tetrazole (CAS 50907-20-5), a certified reference material (molecular formula C7H5FN4, MW 164.14 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine substitution, an aromatic ring system, 5-(3-Fluorophenyl)-2H-tetrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
