Chemical Structure
Description
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.
2-Chloro-1-[2,5-dimethyl-1-(prop-2-yn-1-yl)-1h-pyrrol-3-yl]ethan-1-one (CAS 1155980-26-9), molecular formula C11H12ClNO and molecular weight 209.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-1-[2,5-dimethyl-1-(prop-2-yn-1-yl)-1h-pyrrol-3-yl]ethan-1-one (C11H12ClNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-Chloro-1-[2,5-dimethyl-1-(prop-2-yn-1-yl)-1h-pyrrol-3-yl]ethan-1-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.
