Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 220.01 g/mol gives 2-Iodo-6-methylpyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Iodo-6-methylpyrazine (CAS 58139-06-3), molecular formula C5H5IN2 and molecular weight 220.01 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Iodo-6-methylpyrazine (C5H5IN2) is characterized by a nitrile group, 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), 2-Iodo-6-methylpyrazine 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.
