Caspofungin Impurity 31(5-((3R)-3-Hydroxy-L-Ornithine)-Pneumocandin B0) CAS 150283-04-8

Description

The occurrence of Caspofungin Impurity 31(5-((3R)-3-Hydroxy-L-Ornithine)-Pneumocandin B0) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Caspofungin Impurity 31(5-((3R)-3-Hydroxy-L-Ornithine)-Pneumocandin B0) (CAS 150283-04-8), a pharmacopoeial impurity reference standard (molecular formula C50H82N8O16, MW 1051.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Caspofungin Impurity 31(5-((3R)-3-Hydroxy-L-Ornithine)-Pneumocandin B0) (C50H82N8O16) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 1051.23 g/mol, it falls into the high-molecular-weight range. 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.

As a certified reference material (CRM), Caspofungin Impurity 31(5-((3R)-3-Hydroxy-L-Ornithine)-Pneumocandin B0) 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.
