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 5-Bromo-2-iodo-pyridine-3-carbonitrile (CAS 1346540-97-3), a certified reference material (molecular formula C6H2BrIN2, MW 308.90 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-2-iodo-pyridine-3-carbonitrile (C6H2BrIN2) is characterized by a nitrile group, bromine/iodine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 5-Bromo-2-iodo-pyridine-3-carbonitrile 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.
