Chemical Structure

Alvimopan impurity 15 CAS CATO-C4X-114515 chemical structure

Description

As a certified reference material (CRM), Alvimopan 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.

CATO supplies Alvimopan impurity 15 (CAS CATO-C4X-114515), a pharmacopoeial impurity reference standard (molecular formula C20H23NO3, MW 325.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Alvimopan impurity 15 (C20H23NO3) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
