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.
1-(5-Hydroxy-3-methyl-2-phenylpyrazolidin-1-yl)ethanone (CAS 92522-00-4), molecular formula C12H16N2O2 and molecular weight 220.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-Hydroxy-3-methyl-2-phenylpyrazolidin-1-yl)ethanone (C12H16N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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), 1-(5-Hydroxy-3-methyl-2-phenylpyrazolidin-1-yl)ethanone 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.
