Chemical Structure
Description
2-Amino-4-ethyl-5-methyl-1H-pyrrole-3-carbonitrile (CAS 58121-01-0), molecular formula C8H11N3 and molecular weight 149.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Amino-4-ethyl-5-methyl-1H-pyrrole-3-carbonitrile (C8H11N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).
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-Amino-4-ethyl-5-methyl-1H-pyrrole-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.
