Chemical Structure
Description
2,9-Dimethyl-1,10-phenanthroline dihydrate (CAS 34302-70-0) is a high-purity analytical reference standard with the molecular formula C14H12N2H2O and a molecular weight of 226.28 g/mol.
2,9-Dimethyl-1,10-phenanthroline dihydrate (C14H12N2H2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
