Chemical Structure
Description
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.
CATO supplies 1-(4-Nitro-1h-pyrrole-2-carbonyl)-1,4-diazepan-5-one (CAS 930479-77-9), a certified reference material (molecular formula C10H12N4O4, MW 252.23 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Nitro-1h-pyrrole-2-carbonyl)-1,4-diazepan-5-one (C10H12N4O4) 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).
As a certified reference material (CRM), 1-(4-Nitro-1h-pyrrole-2-carbonyl)-1,4-diazepan-5-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.
