Pemetrexed Impurity CAS 1644286-35-0

Description

Compared with other compounds in its class, the molecular weight of 441.44 g/mol gives Pemetrexed Impurity distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Pemetrexed Impurity (CAS 1644286-35-0) is a high-purity analytical reference standard with the molecular formula C21H23N5O6 and a molecular weight of 441.44 g/mol.

Structurally, Pemetrexed Impurity (C21H23N5O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 441.44 g/mol, it falls into the moderately-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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Pemetrexed Impurity 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.
