Chemical Structure

Docetaxel Impurity 52 CAS 154428-10-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 309.36 g/mol gives Docetaxel Impurity 52 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Docetaxel Impurity 52 (CAS 154428-10-1, C19H19NO3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Docetaxel Impurity 52 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.36 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.

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), Docetaxel Impurity 52 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.
