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-Pentadecylimidazo[1,2-a]pyrimidin-7(1H)-one (CAS 144841-25-8), molecular formula C21H35N3O and molecular weight 345.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Pentadecylimidazo[1,2-a]pyrimidin-7(1H)-one (C21H35N3O) is characterized by a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-Pentadecylimidazo[1,2-a]pyrimidin-7(1H)-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.
