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-1H-pyrrole-2,5-dione 1-methyl-pyrrole-2,5-dione 1h-pyrrole-2,5-dione, 1-methyl- 1h-pyrrole-2,5-dione,1-methyl- 930-88-1 N-Methylmaleimide maleimide, n-methyl- maleimide,n-methyl- maleins|Aure-n-methylimid n-methylmaleimid n-methylmaleinimide.

CATO supplies 1-Methyl-1H-pyrrole-2,5-dione 1-methyl-pyrrole-2,5-dione 1h-pyrrole-2,5-dione, 1-methyl- 1h-pyrrole-2,5-dione,1-methyl- 930-88-1 N-Methylmaleimide maleimide, n-methyl- maleimide,n-methyl- maleins|Aure-n-methylimid n-methylmaleimid n-methylmaleinimide (CAS 930-88-1), a certified reference material (molecular formula C5H5NO2, MW 111.10 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H5NO2, 1-Methyl-1H-pyrrole-2,5-dione 1-methyl-pyrrole-2,5-dione 1h-pyrrole-2,5-dione, 1-methyl- 1h-pyrrole-2,5-dione,1-methyl- 930-88-1 N-Methylmaleimide maleimide, n-methyl- maleimide,n-methyl- maleins|Aure-n-methylimid n-methylmaleimid n-methylmaleinimide contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 111.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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-1H-pyrrole-2,5-dione 1-methyl-pyrrole-2,5-dione 1h-pyrrole-2,5-dione, 1-methyl- 1h-pyrrole-2,5-dione,1-methyl- 930-88-1 N-Methylmaleimide maleimide, n-methyl- maleimide,n-methyl- maleins|Aure-n-methylimid n-methylmaleimid n-methylmaleinimide 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.
