Phenoxymethylpenicillin EP Impurity F (2R,4S) CAS 196701-54-9

Description

The occurrence of Phenoxymethylpenicillin EP Impurity F (2R,4S) is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Phenoxymethylpenicillin EP Impurity F (2R,4S) (CAS 196701-54-9) is a certified pharmaceutical impurity reference standard with the molecular formula C15H20N2O4S and a molecular weight of 324.40 g/mol.

Based on its molecular formula C15H20N2O4S, Phenoxymethylpenicillin EP Impurity F (2R,4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 324.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 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.

As a certified reference material (CRM), Phenoxymethylpenicillin EP Impurity F (2R,4S) 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.
