4-Methoxy-2,5-dioxo-2,5-dihydro-1H-pyrrole-3-carbonitrile CAS 87465-75-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methoxy-2,5-dioxo-2,5-dihydro-1H-pyrrole-3-carbonitrile.

4-Methoxy-2,5-dioxo-2,5-dihydro-1H-pyrrole-3-carbonitrile (CAS 87465-75-6), molecular formula C6H4N2O3 and molecular weight 152.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Methoxy-2,5-dioxo-2,5-dihydro-1H-pyrrole-3-carbonitrile (C6H4N2O3) 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 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.

As a certified reference material (CRM), 4-Methoxy-2,5-dioxo-2,5-dihydro-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.
