Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(Benzenesulfonyl)-4-bromo-1H-pyrrolo[2,3-b]pyridine-2-carbaldehyde (CAS 942920-59-4), a certified reference material (molecular formula C14H9BrN2O3S, MW 365.20 g/mol) for analytical method development and quality control.
The molecular framework of 1-(Benzenesulfonyl)-4-bromo-1H-pyrrolo[2,3-b]pyridine-2-carbaldehyde (C14H9BrN2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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), 1-(Benzenesulfonyl)-4-bromo-1H-pyrrolo[2,3-b]pyridine-2-carbaldehyde 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.
