Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Des-[Oct-γ-Glu-AEEA-AEEA]-Semaglutide.
Des-[Oct-γ-Glu-AEEA-AEEA]-Semaglutide (CAS CATO-C4X-2226112), molecular formula C152H230N42O47 and molecular weight 3397.76 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Des-[Oct-γ-Glu-AEEA-AEEA]-Semaglutide (C152H230N42O47) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
