((2-Hydroxy-5-iodo-1H-indol-3-yl)diazenyl)(pyridin-4-yl)methanone CAS 52540-99-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((2-Hydroxy-5-iodo-1H-indol-3-yl)diazenyl)(pyridin-4-yl)methanone.

((2-Hydroxy-5-iodo-1H-indol-3-yl)diazenyl)(pyridin-4-yl)methanone (CAS 52540-99-5), molecular formula C14H9IN4O2 and molecular weight 392.15 g/mol, is a CATO reference standard with documented purity and traceability.

((2-Hydroxy-5-iodo-1H-indol-3-yl)diazenyl)(pyridin-4-yl)methanone (C14H9IN4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), ((2-Hydroxy-5-iodo-1H-indol-3-yl)diazenyl)(pyridin-4-yl)methanone 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.
