Compared with other compounds in its class, the molecular weight of 414.67 g/mol gives Thioctic acid Impurity 15 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Thioctic acid Impurity 15 (CAS CATO-C4X-152615, C16H30O4S4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Thioctic acid Impurity 15 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 414.67 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), Thioctic acid Impurity 15 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.
