Chemical Structure

Carfilzomib Impurity 14 CAS 3235-69-6 chemical structure

Description

Structurally, Carfilzomib Impurity 14 (C6H11NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 145.16 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Carfilzomib Impurity 14 (CAS 3235-69-6) is a certified pharmaceutical impurity reference standard with the molecular formula C6H11NO3 and a molecular weight of 145.16 g/mol.

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 14 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.
