Compared with other compounds in its class, the molecular weight of 528.58 g/mol gives Tobramycin-D, 18O Acetic Acid Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tobramycin-D, 18O Acetic Acid Salt (CAS CATO-CCAD302249), a certified reference material (molecular formula C18H36DN5O8[18O] x·C2H4O2, MW 528.58 g/mol) for analytical method development and quality control.
Tobramycin-D, 18O Acetic Acid Salt (C18H36DN5O8[18O] x·C2H4O2) contains deuterium isotope labeling, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Tobramycin-D, 18O Acetic Acid Salt 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.
