Chemical Structure

Des-His(1)-Semaglutide CAS CATO-C4X-2226216 chemical structure

Description

Des-His(1)-Semaglutide (CAS CATO-C4X-2226216) is a high-purity analytical reference standard with the molecular formula C181H284N42O58 and a molecular weight of 3976.44 g/mol.

Based on its molecular formula C181H284N42O58, Des-His(1)-Semaglutide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 3976.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
