Chemical Structure
Description
As a certified reference material (CRM), Fragment-[3-31]-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.
Fragment-[3-31]-Semaglutide (CAS CATO-C4X-2226113) is a high-purity analytical reference standard with the molecular formula C177H277N41O57 and a molecular weight of 3891.33 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Fragment-[3-31]-Semaglutide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 3891.33 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
