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.
2-Iodo-3-nitro-1-(phenylsulfonyl)-1H-indole (CAS 927807-86-1) is a high-purity analytical reference standard with the molecular formula C14H9IN2O4S and a molecular weight of 428.20 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution, 2-Iodo-3-nitro-1-(phenylsulfonyl)-1H-indole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.20 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.
As a certified reference material (CRM), 2-Iodo-3-nitro-1-(phenylsulfonyl)-1H-indole 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.
