Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 401.48 g/mol gives Meropenem Trihydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Meropenem Trihydrate (CAS 119478-56-7), a certified reference material (molecular formula C17H25N3O5SH2O, MW 401.48 g/mol) for analytical method development and quality control.
Meropenem Trihydrate (C17H25N3O5SH2O) contains a steroid core, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Meropenem Trihydrate 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.
