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 22.
Carfilzomib Impurity 22 (CAS 2049025-45-6) is a certified pharmaceutical impurity reference standard with the molecular formula C40H57N5O7 and a molecular weight of 719.91 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Carfilzomib Impurity 22 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 719.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Carfilzomib Impurity 22 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
