Chemical Structure
Description
CATO supplies 5-Methyl-2,3-dihydroimidazo[2,1-a]phthalazin-6(5H)-one (CAS 57100-17-1), a certified reference material (molecular formula C11H11N3O, MW 201.22 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methyl-2,3-dihydroimidazo[2,1-a]phthalazin-6(5H)-one (C11H11N3O) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
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), 5-Methyl-2,3-dihydroimidazo[2,1-a]phthalazin-6(5H)-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.
