Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Dibromo-2,2,5,5-tetramethyl-1-(l1-oxidaneyl)-2,5-dihydro-1H-pyrrole.
CATO supplies 3,4-Dibromo-2,2,5,5-tetramethyl-1-(l1-oxidaneyl)-2,5-dihydro-1H-pyrrole (CAS 78033-68-8), a certified reference material (molecular formula C8H12Br2NO, MW 297.99 g/mol) for analytical method development and quality control.
Structurally, 3,4-Dibromo-2,2,5,5-tetramethyl-1-(l1-oxidaneyl)-2,5-dihydro-1H-pyrrole (C8H12Br2NO) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 297.99 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3,4-Dibromo-2,2,5,5-tetramethyl-1-(l1-oxidaneyl)-2,5-dihydro-1H-pyrrole 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.
