Chemical Structure
Description
As a certified reference material (CRM), 3,4-Dibromo-1-isopropyl-1H-pyrrol-2(5H)-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.
3,4-Dibromo-1-isopropyl-1H-pyrrol-2(5H)-one (CAS 1706429-01-7) is a high-purity analytical reference standard with the molecular formula C7H9Br2NO and a molecular weight of 282.96 g/mol.
3,4-Dibromo-1-isopropyl-1H-pyrrol-2(5H)-one (C7H9Br2NO) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
