Chemical Structure
Description
As a certified reference material (CRM), Loxoprofen Sodium Salt Dihydrate 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.
Loxoprofen Sodium Salt Dihydrate (CAS 226721-96-6) is a high-purity analytical reference standard with the molecular formula C15H17O3NaH2O and a molecular weight of 286.30 g/mol.
Loxoprofen Sodium Salt Dihydrate (C15H17O3NaH2O) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
