Chemical Structure

3-Bromo-6-iodopyrazine-2-carbonitrile CAS 1823919-86-3 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 3-Bromo-6-iodopyrazine-2-carbonitrile.

CATO supplies 3-Bromo-6-iodopyrazine-2-carbonitrile (CAS 1823919-86-3), a certified reference material (molecular formula C5HBrIN3, MW 309.89 g/mol) for analytical method development and quality control.

The molecular framework of 3-Bromo-6-iodopyrazine-2-carbonitrile (C5HBrIN3) is characterized by 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 3-Bromo-6-iodopyrazine-2-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.
