Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Bromo-3-iodo-4-methyl-1H-pyrrolo[3,2-c]pyridine.
7-Bromo-3-iodo-4-methyl-1H-pyrrolo[3,2-c]pyridine (CAS 1621963-71-0) is a high-purity analytical reference standard with the molecular formula C8H6BrIN2 and a molecular weight of 336.96 g/mol.
The molecular framework of 7-Bromo-3-iodo-4-methyl-1H-pyrrolo[3,2-c]pyridine (C8H6BrIN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine/iodine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-Bromo-3-iodo-4-methyl-1H-pyrrolo[3,2-c]pyridine 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.
