Chemical Structure
Description
As a certified reference material (CRM), 2-Bromo-N,N-dimethyl-1H-pyrrole-1-sulfonamide 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.
2-Bromo-N,N-dimethyl-1H-pyrrole-1-sulfonamide (CAS 1881293-00-0), molecular formula C6H9BrN2O2S and molecular weight 253.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-N,N-dimethyl-1H-pyrrole-1-sulfonamide (C6H9BrN2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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.
