Chemical Structure
Description
As a certified reference material (CRM), 4-(Pyrrolidin-1-yl)-1-(thiazol-2-yl)butan-1-one hydrobromide 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.
CATO supplies 4-(Pyrrolidin-1-yl)-1-(thiazol-2-yl)butan-1-one hydrobromide (CAS 33524-04-8), a certified reference material (molecular formula C11H16N2OSHBr, MW 305.23 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Pyrrolidin-1-yl)-1-(thiazol-2-yl)butan-1-one hydrobromide (C11H16N2OSHBr) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
