Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-((5-Bromo-2-fluorophenyl)sulfonyl)pyrrolidine.
1-((5-Bromo-2-fluorophenyl)sulfonyl)pyrrolidine (CAS 1436232-71-1), molecular formula C10H11BrFNO2S and molecular weight 308.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H11BrFNO2S, 1-((5-Bromo-2-fluorophenyl)sulfonyl)pyrrolidine contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 308.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1-((5-Bromo-2-fluorophenyl)sulfonyl)pyrrolidine 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.
