The occurrence of Sulindac EP Impurity C-d3 is closely related to deuterium isotope labeling, a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
As a process- or degradation-related impurity, Sulindac EP Impurity C-d3 (CAS 250608-66-3, C20H14D3FO2S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to deuterium isotope labeling, a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Sulindac EP Impurity C-d3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 343.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Sulindac EP Impurity C-d3 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.
