Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 464.47 g/mol gives Diclofenac Dodecyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diclofenac Dodecyl Ester (CAS 2731820-79-2) is a high-purity analytical reference standard with the molecular formula C26H35Cl2NO2 and a molecular weight of 464.47 g/mol.
Diclofenac Dodecyl Ester (C26H35Cl2NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Diclofenac Dodecyl Ester 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.
