Caspofungin EP Impurity B Acetate(RRT=1.50) CAS 314080-31-4 (free base)

Description

Compared with other compounds in its class, the molecular weight of 1111.30 g/mol gives Caspofungin EP Impurity B Acetate(RRT=1.50) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Caspofungin EP Impurity B Acetate(RRT=1.50) (CAS 314080-31-4 (free base)), a pharmacopoeial impurity reference standard (molecular formula C50H82N8O16C2H4O2, MW 1111.30 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Caspofungin EP Impurity B Acetate(RRT=1.50) (C50H82N8O16C2H4O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Caspofungin EP Impurity B Acetate(RRT=1.50) 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.
