Chemical Structure

Thioctic Acid Impurity 50 CAS CATO-C4X-152650 chemical structure

Description

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.

Thioctic Acid Impurity 50 (CAS CATO-C4X-152650) is a certified pharmaceutical impurity reference standard with the molecular formula C10H18O3 and a molecular weight of 186.25 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Thioctic Acid Impurity 50 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.25 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.

As a certified reference material (CRM), Thioctic Acid Impurity 50 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.
