Chemical Structure
Description
As a certified reference material (CRM), Ethyl 3-cyano-2-methyl-1H-pyrrole-1-carboxylate 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.
Ethyl 3-cyano-2-methyl-1H-pyrrole-1-carboxylate (CAS 856120-96-2) is a high-purity analytical reference standard with the molecular formula C9H10N2O2 and a molecular weight of 178.19 g/mol.
The molecular framework of Ethyl 3-cyano-2-methyl-1H-pyrrole-1-carboxylate (C9H10N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
