Chemical Structure
Description
The occurrence of S-Adenosyl-L-Methionine Impurity 5 is closely related to a nitrogen-containing heterocyclic scaffold, 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.
CATO supplies S-Adenosyl-L-Methionine Impurity 5 (CAS CATO-C4X-13815), a pharmacopoeial impurity reference standard (molecular formula C14H23N6O3SC4H9O6S2, MW 572.67 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, S-Adenosyl-L-Methionine Impurity 5 (C14H23N6O3SC4H9O6S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 572.67 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), S-Adenosyl-L-Methionine Impurity 5 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.
