Rotigotine Impurity 40 CAS 102121-00-6

Description

Compared with other compounds in its class, the molecular weight of 315.47 g/mol gives Rotigotine Impurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Rotigotine Impurity 40 (CAS 102121-00-6) is a certified pharmaceutical impurity reference standard with the molecular formula C19H25NOS and a molecular weight of 315.47 g/mol.

Rotigotine Impurity 40 (C19H25NOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
