Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 405.40 g/mol gives Amoxicillin EP Impurity D Na distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Amoxicillin EP Impurity D Na (CAS 1642559-71-4), a certified reference material (molecular formula C16H20N3O6SNa, MW 405.40 g/mol) for analytical method development and quality control.
Structurally, Amoxicillin EP Impurity D Na (C16H20N3O6SNa) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 405.40 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Amoxicillin EP Impurity D Na 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.
