1-Methyl-3-phenyl-1,5-dihydro-2H-pyrrol-2-one CAS 55164-56-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Methyl-3-phenyl-1,5-dihydro-2H-pyrrol-2-one.

CATO supplies 1-Methyl-3-phenyl-1,5-dihydro-2H-pyrrol-2-one (CAS 55164-56-2), a certified reference material (molecular formula C11H11NO, MW 173.21 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-Methyl-3-phenyl-1,5-dihydro-2H-pyrrol-2-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 173.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 1-Methyl-3-phenyl-1,5-dihydro-2H-pyrrol-2-one 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.
