Description
CATO supplies 139072-17-6 2-Fluoro-4-iodophenyl isocyanate DTXSID40404886 (CAS 139072-17-6), a certified reference material (molecular formula C7H3FINO, MW 263.01 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system, 139072-17-6 2-Fluoro-4-iodophenyl isocyanate DTXSID40404886 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.01 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.
As a certified reference material (CRM), 139072-17-6 2-Fluoro-4-iodophenyl isocyanate DTXSID40404886 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.
