Chemical Structure
Description
The occurrence of Thioctic Acid Impurity 71 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Thioctic Acid Impurity 71 (CAS CATO-C4X-152671) is a certified pharmaceutical impurity reference standard with the molecular formula C8H14O3S2 and a molecular weight of 222.32 g/mol.
Based on its molecular formula C8H14O3S2, Thioctic Acid Impurity 71 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 222.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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 71 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.
