Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 232.02 g/mol gives 3-Iodo-1-methyl-1H-pyrrole-2-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Iodo-1-methyl-1H-pyrrole-2-carbonitrile (CAS 1823919-87-4), molecular formula C6H5IN2 and molecular weight 232.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Iodo-1-methyl-1H-pyrrole-2-carbonitrile (C6H5IN2) is characterized by a nitrile group, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 3-Iodo-1-methyl-1H-pyrrole-2-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
