Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 258.07 g/mol gives 13C6-Diclofenac Sodium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
13C6-Diclofenac Sodium (CAS 1261393-73-0) is a high-purity analytical reference standard with the molecular formula C8[13C]6H10Cl2NO2 Na and a molecular weight of 258.07 g/mol.
The molecular framework of 13C6-Diclofenac Sodium (C8[13C]6H10Cl2NO2 Na) is characterized by a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
