Napipitant‌ Impurity 3 CAS CATO-C4X-34853

Description

Compared with other compounds in its class, the molecular weight of 744.70 g/mol gives Napipitant‌ Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Napipitant‌ Impurity 3 (CAS CATO-C4X-34853), molecular formula C35H43F6N4O5P and molecular weight 744.70 g/mol, is a CATO reference standard with documented purity and traceability.

Napipitant‌ Impurity 3 (C35H43F6N4O5P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Napipitant‌ Impurity 3 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.
