Chemical Structure

Methyl 4-hydroxy-2-oxo-2,5-dihydro-1H-pyrrole-3-carboxylate CAS 37772-85-3 chemical structure

Description

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

Methyl 4-hydroxy-2-oxo-2,5-dihydro-1H-pyrrole-3-carboxylate (CAS 37772-85-3) is a high-purity analytical reference standard with the molecular formula C6H7NO4 and a molecular weight of 157.12 g/mol.

The molecular framework of Methyl 4-hydroxy-2-oxo-2,5-dihydro-1H-pyrrole-3-carboxylate (C6H7NO4) 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), Methyl 4-hydroxy-2-oxo-2,5-dihydro-1H-pyrrole-3-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.
