Chemical Structure

Carfilzomib Impurity 61 CAS 2049025-67-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Carfilzomib Impurity 61.

CATO supplies Carfilzomib Impurity 61 (CAS 2049025-67-2), a pharmacopoeial impurity reference standard (molecular formula C40H57N5O7, MW 719.91 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C40H57N5O7, Carfilzomib Impurity 61 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 719.91 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Carfilzomib Impurity 61 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.
