3,8-Dimethyl-1,10-diphenoxy-4,7-phenanthroline CAS 7250-17-1

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.

3,8-Dimethyl-1,10-diphenoxy-4,7-phenanthroline (CAS 7250-17-1) is a high-purity analytical reference standard with the molecular formula C26H20N2O2 and a molecular weight of 392.45 g/mol.

3,8-Dimethyl-1,10-diphenoxy-4,7-phenanthroline (C26H20N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3,8-Dimethyl-1,10-diphenoxy-4,7-phenanthroline 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.
