Compared with other compounds in its class, the molecular weight of 151.21 g/mol gives 4-(1-Methyl-1h-pyrrol-2-yl)butan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(1-Methyl-1h-pyrrol-2-yl)butan-2-one (CAS 41711-74-4), a certified reference material (molecular formula C9H13NO, MW 151.21 g/mol) for analytical method development and quality control.
The molecular framework of 4-(1-Methyl-1h-pyrrol-2-yl)butan-2-one (C9H13NO) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-(1-Methyl-1h-pyrrol-2-yl)butan-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.
