Alvimopan impurity 13 CAS CATO-C4X-114513

Description

Compared with other compounds in its class, the molecular weight of 381.51 g/mol gives Alvimopan impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Alvimopan impurity 13 (CAS CATO-C4X-114513) is a certified pharmaceutical impurity reference standard with the molecular formula C24H31NO3 and a molecular weight of 381.51 g/mol.

Alvimopan impurity 13 (C24H31NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.

As a certified reference material (CRM), Alvimopan impurity 13 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.
