Chemical Structure
Description
1-Methyl-1,10-phenanthrolin-2(1H)-one (CAS 31535-89-4), molecular formula C13H10N2O and molecular weight 210.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Methyl-1,10-phenanthrolin-2(1H)-one (C13H10N2O) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
