Chemical Structure
Description
The occurrence of Atracurium EP Impurity K 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.
Atracurium EP Impurity K (CAS CATO-C4X-185057) is a certified pharmaceutical impurity reference standard with the molecular formula C54H74N2O12 and a molecular weight of 943.17 g/mol.
Structurally, Atracurium EP Impurity K (C54H74N2O12) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 943.17 g/mol, it falls into the high-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.
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), Atracurium EP Impurity K 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.
