Description
As a certified reference material (CRM), [pGlu] Semaglutide 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 [pGlu] Semaglutide (CAS CATO-C4X-2226288), a certified reference material (molecular formula C142H214N38O44, MW 3157.45 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, [pGlu] Semaglutide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 3157.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
