Description
As a certified reference material (CRM), Ampicillin-d5 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.
CATO supplies Ampicillin-d5 (CAS 1426173-65-0), a certified reference material (molecular formula C16H14D5N3O4S, MW 354.44 g/mol) for analytical method development and quality control.
Structurally, Ampicillin-d5 (C16H14D5N3O4S) contains deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 354.44 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.
